	/**
	 * DataTables API class - used to control and interface with  one or more
	 * DataTables enhanced tables.
	 *
	 * The API class is heavily based on jQuery, presenting a chainable interface
	 * that you can use to interact with tables. Each instance of the API class has
	 * a "context" - i.e. the tables that it will operate on. This could be a single
	 * table, all tables on a page or a sub-set thereof.
	 *
	 * Additionally the API is designed to allow you to easily work with the data in
	 * the tables, retrieving and manipulating it as required. This is done by
	 * presenting the API class as an array like interface. The contents of the
	 * array depend upon the actions requested by each method (for example
	 * `rows().nodes()` will return an array of nodes, while `rows().data()` will
	 * return an array of objects or arrays depending upon your table's
	 * configuration). The API object has a number of array like methods (`push`,
	 * `pop`, `reverse` etc) as well as additional helper methods (`each`, `pluck`,
	 * `unique` etc) to assist your working with the data held in a table.
	 *
	 * Most methods (those which return an Api instance) are chainable, which means
	 * the return from a method call also has all of the methods available that the
	 * top level object had. For example, these two calls are equivalent:
	 *
	 *     // Not chained
	 *     api.row.add( {...} );
	 *     api.draw();
	 *
	 *     // Chained
	 *     api.row.add( {...} ).draw();
	 *
	 * @class DataTable.Api
	 * @param {array|object|string|jQuery} context DataTable identifier. This is
	 *   used to define which DataTables enhanced tables this API will operate on.
	 *   Can be one of:
	 *
	 *   * `string` - jQuery selector. Any DataTables' matching the given selector
	 *     with be found and used.
	 *   * `node` - `TABLE` node which has already been formed into a DataTable.
	 *   * `jQuery` - A jQuery object of `TABLE` nodes.
	 *   * `object` - DataTables settings object
	 * @param {array} [data] Data to initialise the Api instance with.
	 *
	 * @example
	 *   // Direct initialisation during DataTables construction
	 *   var api = $('#example').DataTable();
	 *
	 * @example
	 *   // Initialisation using a DataTables jQuery object
	 *   var api = $('#example').dataTable().api();

		/**
		 * DataTables can be instructed to load data to display in the table from a

		 *
		 * The `ajax` property has three different modes of operation, depending on
		 * how it is defined. These are:
		 *
		 * * `string` - Set the URL from where the data should be loaded from.
		 * * `object` - Define properties for `jQuery.ajax`.
		 * * `function` - Custom data get function
		 *
		 * `string`
		 * --------
		 *
		 * As a string, the `ajax` property simply defines the URL from which
		 * DataTables will load data.
		 *
		 * `object`
		 * --------
		 *
		 * As an object, the parameters in the object are passed to
		 * [jQuery.ajax](http://api.jquery.com/jQuery.ajax/) allowing fine control
		 * of the Ajax request. DataTables has a number of default parameters which
		 * you can override using this option. Please refer to the jQuery
		 * documentation for a full description of the options available, although
		 * the following parameters provide additional options in DataTables or
		 * require special consideration:
		 *
		 * * `data` - As with jQuery, `data` can be provided as an object, but it
		 *   can also be used as a function to manipulate the data DataTables sends
		 *   to the server. The function takes a single parameter, an object of
		 *   parameters with the values that DataTables has readied for sending. An
		 *   object may be returned which will be merged into the DataTables
		 *   defaults, or you can add the items to the object that was passed in and
		 *   not return anything from the function. This supersedes `fnServerParams`
		 *   from DataTables 1.9-.
		 *
		 * * `dataSrc` - By default DataTables will look for the property `data` (or
		 *   `aaData` for compatibility with DataTables 1.9-) when obtaining data
		 *   from an Ajax source or for server-side processing - this parameter
		 *   allows that property to be changed. You can use Javascript dotted
		 *   object notation to get a data source for multiple levels of nesting, or
		 *   it my be used as a function. As a function it takes a single parameter,
		 *   the JSON returned from the server, which can be manipulated as
		 *   required, with the returned value being that used by DataTables as the
		 *   data source for the table. This supersedes `sAjaxDataProp` from
		 *   DataTables 1.9-.
		 *
		 * * `success` - Should not be overridden it is used internally in
		 *   DataTables. To manipulate / transform the data returned by the server
		 *   use `ajax.dataSrc`, or use `ajax` as a function (see below).
		 *
		 * `function`
		 * ----------
		 *
		 * As a function, making the Ajax call is left up to yourself allowing
		 * complete control of the Ajax request. Indeed, if desired, a method other
		 * than Ajax could be used to obtain the required data, such as Web storage
		 * or an AIR database.
		 *
		 * The function is given four parameters and no return is required. The
		 * parameters are:
		 *
		 * 1. _object_ - Data to send to the server
		 * 2. _function_ - Callback function that must be executed when the required
		 *    data has been obtained. That data should be passed into the callback
		 *    as the only parameter
		 * 3. _object_ - DataTables settings object for the table
		 *
		 * Note that this supersedes `fnServerData` from DataTables 1.9-.

		/**
		 * This property can be used to read data from any data source property,
		 * including deeply nested objects / properties. `data` can be given in a
		 * number of different ways which effect its behaviour:
		 *
		 * * `integer` - treated as an array index for the data source. This is the
		 *   default that DataTables uses (incrementally increased for each column).
		 * * `string` - read an object property from the data source. There are
		 *   three 'special' options that can be used in the string to alter how
		 *   DataTables reads the data from the source object:
		 *    * `.` - Dotted Javascript notation. Just as you use a `.` in
		 *      Javascript to read from nested objects, so to can the options
		 *      specified in `data`. For example: `browser.version` or
		 *      `browser.name`. If your object parameter name contains a period, use
		 *      `\\` to escape it - i.e. `first\\.name`.
		 *    * `[]` - Array notation. DataTables can automatically combine data
		 *      from and array source, joining the data with the characters provided
		 *      between the two brackets. For example: `name[, ]` would provide a
		 *      comma-space separated list from the source array. If no characters
		 *      are provided between the brackets, the original array source is
		 *      returned.
		 *    * `()` - Function notation. Adding `()` to the end of a parameter will
		 *      execute a function of the name given. For example: `browser()` for a
		 *      simple function on the data source, `browser.version()` for a
		 *      function in a nested property or even `browser().version` to get an
		 *      object property if the function called returns an object. Note that
		 *      function notation is recommended for use in `render` rather than
		 *      `data` as it is much simpler to use as a renderer.
		 * * `null` - use the original data source for the row rather than plucking
		 *   data directly from it. This action has effects on two other
		 *   initialisation options:
		 *    * `defaultContent` - When null is given as the `data` option and
		 *      `defaultContent` is specified for the column, the value defined by
		 *      `defaultContent` will be used for the cell.
		 *    * `render` - When null is used for the `data` option and the `render`
		 *      option is specified for the column, the whole data source for the
		 *      row is used for the renderer.
		 * * `function` - the function given will be executed whenever DataTables
		 *   needs to set or get the data for a cell in the column. The function
		 *   takes three parameters:
		 *    * Parameters:
		 *      * `{array|object}` The data source for the row
		 *      * `{string}` The type call data requested - this will be 'set' when
		 *        setting data or 'filter', 'display', 'type', 'sort' or undefined
		 *        when gathering data. Note that when `undefined` is given for the
		 *        type DataTables expects to get the raw data for the object back<
		 *      * `{*}` Data to set when the second parameter is 'set'.
		 *    * Return:
		 *      * The return value from the function is not required when 'set' is
		 *        the type of call, but otherwise the return is what will be used
		 *        for the data requested.
		 *
		 * Note that `data` is a getter and setter option. If you just require
		 * formatting of data for output, you will likely want to use `render` which
		 * is simply a getter and thus simpler to use.
		 *
		 * Note that prior to DataTables 1.9.2 `data` was called `mDataProp`. The
		 * name change reflects the flexibility of this property and is consistent
		 * with the naming of mRender. If 'mDataProp' is given, then it will still
		 * be used by DataTables, as it automatically maps the old name to the new
		 * if required.

//	3. Use the same single mechanism to support "private" and "user" data.
//	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
//	5. Avoid exposing implementation details on user objects (eg. expando properties)

/**
 * DataTables API class - used to control and interface with  one or more
 * DataTables enhanced tables.
 *
 * The API class is heavily based on jQuery, presenting a chainable interface
 * that you can use to interact with tables. Each instance of the API class has
 * a "context" - i.e. the tables that it will operate on. This could be a single
 * table, all tables on a page or a sub-set thereof.
 *
 * Additionally the API is designed to allow you to easily work with the data in
 * the tables, retrieving and manipulating it as required. This is done by
 * presenting the API class as an array like interface. The contents of the
 * array depend upon the actions requested by each method (for example
 * `rows().nodes()` will return an array of nodes, while `rows().data()` will
 * return an array of objects or arrays depending upon your table's
 * configuration). The API object has a number of array like methods (`push`,
 * `pop`, `reverse` etc) as well as additional helper methods (`each`, `pluck`,
 * `unique` etc) to assist your working with the data held in a table.
 *
 * Most methods (those which return an Api instance) are chainable, which means
 * the return from a method call also has all of the methods available that the
 * top level object had. For example, these two calls are equivalent:
 *
 *     // Not chained
 *     api.row.add( {...} );
 *     api.draw();
 *
 *     // Chained
 *     api.row.add( {...} ).draw();
 *
 * @class DataTable.Api
 * @param {array|object|string|jQuery} context DataTable identifier. This is
 *   used to define which DataTables enhanced tables this API will operate on.
 *   Can be one of:
 *
 *   * `string` - jQuery selector. Any DataTables' matching the given selector
 *     with be found and used.
 *   * `node` - `TABLE` node which has already been formed into a DataTable.
 *   * `jQuery` - A jQuery object of `TABLE` nodes.
 *   * `object` - DataTables settings object
 * @param {array} [data] Data to initialise the Api instance with.
 *
 * @example
 *   // Direct initialisation during DataTables construction
 *   var api = $('#example').DataTable();
 *
 * @example
 *   // Initialisation using a DataTables jQuery object
 *   var api = $('#example').dataTable().api();
 *
 * @example
 *   // Initialisation as a constructor
 *   var api = new $.fn.DataTable.Api( 'table.dataTable' );

	/**
	 * DataTables can be instructed to load data to display in the table from a
	 * Ajax source. This option defines how that Ajax call is made and where to.
	 *
	 * The `ajax` property has three different modes of operation, depending on
	 * how it is defined. These are:
	 *
	 * * `string` - Set the URL from where the data should be loaded from.
	 * * `object` - Define properties for `jQuery.ajax`.
	 * * `function` - Custom data get function
	 *
	 * `string`
	 * --------
	 *
	 * As a string, the `ajax` property simply defines the URL from which
	 * DataTables will load data.
	 *
	 * `object`
	 * --------
	 *
	 * As an object, the parameters in the object are passed to
	 * [jQuery.ajax](https://api.jquery.com/jQuery.ajax/) allowing fine control
	 * of the Ajax request. DataTables has a number of default parameters which
	 * you can override using this option. Please refer to the jQuery
	 * documentation for a full description of the options available, although
	 * the following parameters provide additional options in DataTables or
	 * require special consideration:
	 *
	 * * `data` - As with jQuery, `data` can be provided as an object, but it
	 *   can also be used as a function to manipulate the data DataTables sends
	 *   to the server. The function takes a single parameter, an object of
	 *   parameters with the values that DataTables has readied for sending. An
	 *   object may be returned which will be merged into the DataTables
	 *   defaults, or you can add the items to the object that was passed in and
	 *   not return anything from the function. This supersedes `fnServerParams`
	 *   from DataTables 1.9-.
	 *
	 * * `dataSrc` - By default DataTables will look for the property `data` (or
	 *   `aaData` for compatibility with DataTables 1.9-) when obtaining data
	 *   from an Ajax source or for server-side processing - this parameter
	 *   allows that property to be changed. You can use Javascript dotted
	 *   object notation to get a data source for multiple levels of nesting, or
	 *   it my be used as a function. As a function it takes a single parameter,
	 *   the JSON returned from the server, which can be manipulated as
	 *   required, with the returned value being that used by DataTables as the
	 *   data source for the table. This supersedes `sAjaxDataProp` from
	 *   DataTables 1.9-.
	 *
	 * * `success` - Should not be overridden it is used internally in
	 *   DataTables. To manipulate / transform the data returned by the server
	 *   use `ajax.dataSrc`, or use `ajax` as a function (see below).
	 *
	 * `function`
	 * ----------
	 *
	 * As a function, making the Ajax call is left up to yourself allowing
	 * complete control of the Ajax request. Indeed, if desired, a method other
	 * than Ajax could be used to obtain the required data, such as Web storage
	 * or an AIR database.
	 *
	 * The function is given four parameters and no return is required. The
	 * parameters are:
	 *
	 * 1. _object_ - Data to send to the server
	 * 2. _function_ - Callback function that must be executed when the required
	 *    data has been obtained. That data should be passed into the callback
	 *    as the only parameter
	 * 3. _object_ - DataTables settings object for the table
	 *
	 * Note that this supersedes `fnServerData` from DataTables 1.9-.

	 * This property can be used to read data from any data source property,
	 * including deeply nested objects / properties. `data` can be given in a
	 * number of different ways which effect its behaviour:
	 *
	 * * `integer` - treated as an array index for the data source. This is the
	 *   default that DataTables uses (incrementally increased for each column).
	 * * `string` - read an object property from the data source. There are
	 *   three 'special' options that can be used in the string to alter how
	 *   DataTables reads the data from the source object:
	 *    * `.` - Dotted Javascript notation. Just as you use a `.` in
	 *      Javascript to read from nested objects, so to can the options
	 *      specified in `data`. For example: `browser.version` or
	 *      `browser.name`. If your object parameter name contains a period, use
	 *      `\\` to escape it - i.e. `first\\.name`.
	 *    * `[]` - Array notation. DataTables can automatically combine data
	 *      from and array source, joining the data with the characters provided
	 *      between the two brackets. For example: `name[, ]` would provide a
	 *      comma-space separated list from the source array. If no characters
	 *      are provided between the brackets, the original array source is
	 *      returned.
	 *    * `()` - Function notation. Adding `()` to the end of a parameter will
	 *      execute a function of the name given. For example: `browser()` for a
	 *      simple function on the data source, `browser.version()` for a
	 *      function in a nested property or even `browser().version` to get an
	 *      object property if the function called returns an object. Note that
	 *      function notation is recommended for use in `render` rather than
	 *      `data` as it is much simpler to use as a renderer.
	 * * `null` - use the original data source for the row rather than plucking
	 *   data directly from it. This action has effects on two other
	 *   initialisation options:
	 *    * `defaultContent` - When null is given as the `data` option and
	 *      `defaultContent` is specified for the column, the value defined by
	 *      `defaultContent` will be used for the cell.
	 *    * `render` - When null is used for the `data` option and the `render`
	 *      option is specified for the column, the whole data source for the
	 *      row is used for the renderer.
	 * * `function` - the function given will be executed whenever DataTables
	 *   needs to set or get the data for a cell in the column. The function
	 *   takes three parameters:
	 *    * Parameters:
	 *      * `{array|object}` The data source for the row
	 *      * `{string}` The type call data requested - this will be 'set' when
	 *        setting data or 'filter', 'display', 'type', 'sort' or undefined
	 *        when gathering data. Note that when `undefined` is given for the
	 *        type DataTables expects to get the raw data for the object back<
	 *      * `{*}` Data to set when the second parameter is 'set'.
	 *    * Return:
	 *      * The return value from the function is not required when 'set' is
	 *        the type of call, but otherwise the return is what will be used
	 *        for the data requested.
	 *
	 * Note that `data` is a getter and setter option. If you just require
	 * formatting of data for output, you will likely want to use `render` which
	 * is simply a getter and thus simpler to use.
	 *
	 * Note that prior to DataTables 1.9.2 `data` was called `mDataProp`. The
	 * name change reflects the flexibility of this property and is consistent
	 * with the naming of mRender. If 'mDataProp' is given, then it will still
	 * be used by DataTables, as it automatically maps the old name to the new
	 * if required.

	/**
	 * This property is the rendering partner to `data` and it is suggested that
	 * when you want to manipulate data for display (including filtering,
	 * sorting etc) without altering the underlying data for the table, use this
	 * property. `render` can be considered to be the the read only companion to
	 * `data` which is read / write (then as such more complex). Like `data`
	 * this option can be given in a number of different ways to effect its
	 * behaviour:
	 *
	 * * `integer` - treated as an array index for the data source. This is the
	 *   default that DataTables uses (incrementally increased for each column).

	 *      Javascript to read from nested objects, so to can the options
	 *      specified in `data`. For example: `browser.version` or

	 *      function in a nested property or even `browser().version` to get an
	 *      object property if the function called returns an object.
	 * * `object` - use different data for the different data types requested by
	 *   DataTables ('filter', 'display', 'type' or 'sort'). The property names
	 *   of the object is the data type the property refers to and the value can
	 *   defined using an integer, string or function using the same rules as
	 *   `render` normally does. Note that an `_` option _must_ be specified.
	 *   This is the default value to use if you haven't specified a value for
	 *   the data type requested by DataTables.
	 * * `function` - the function given will be executed whenever DataTables
	 *   needs to set or get the data for a cell in the column. The function
	 *   takes three parameters:
	 *    * Parameters:
	 *      * {array|object} The data source for the row (based on `data`)

	 *        'display', 'type' or 'sort'.

	 *        `data`)
	 *    * Return:
	 *      * The return value from the function is what will be used for the
	 *        data requested.
