  /**
   * 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' );

     *   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).
     * * `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.
     * * `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`)
     *      * {string} The type call data requested - this will be 'filter',
     *        'display', 'type' or 'sort'.
     *      * {array|object} The full data source for the row (not based on
     *        `data`)
     *    * Return:
     *      * The return value from the function is what will be used for the
     *        data requested.

     * descriptions (what each button will do).
     *
     * Pagination types (the four built in options and any additional plug-in
     * options defined here) can be used through the `paginationType`
     * initialisation parameter.

     *
     * 1. `{int} page` The current page index
     * 2. `{int} pages` The number of pages in the table
     *
     * Each function is expected to return an array where each element of the
     * array can be one of:

     * * `first` - Jump to first page when activated
     * * `last` - Jump to last page when activated
     * * `previous` - Show previous page when activated

     * * `{int}` - Show page of the index given
     * * `{array}` - A nested array containing the above elements to add a
     *   containing 'DIV' element (might be useful for styling).

     * Note that DataTables v1.9- used this object slightly differently whereby
     * an object with two functions would be defined for each plug-in. That
     * ability is still supported by DataTables 1.10+ to provide backwards

     * Ordering plug-ins - custom data source
     *
     * The extension options for ordering of data available here is complimentary
     * to the default type based ordering that DataTables typically uses. It
     * allows much greater control over the the data that is being used to
     * order a column, but is necessarily therefore more complex.
     *
     * This type of ordering is useful if you want to do ordering based on data
     * live from the DOM (for example the contents of an 'input' element) rather
     * than just the static string that DataTables knows of.
     *
     * The way these plug-ins work is that you create an array of the values you
     * wish to be ordering for the column in question and then return that
     * array. The data in the array much be in the index order of the rows in
     * the table (not the currently ordering order!). Which order data gathering
     * function is run here depends on the `dt-init columns.orderDataType`
     * parameter that is used for the column (if any).
     *
     * The functions defined take two parameters:
     *
     * 1. `{object}` DataTables settings object: see
     *    {@link DataTable.models.oSettings}
     * 2. `{int}` Target column index
     *

     *
     * * `{array}` Data for the column to be ordering upon
