    /**
     * 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

       * 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](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,

       * 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.

         * Type based search formatting.
         *
         * The type based searching functions can be used to pre-format the
         * data to be search on. For example, it can be used to strip HTML
         * tags or to de-format telephone numbers for numeric only searching.
         *
         * Note that is a search is not defined for a column of a given type,
         * no search formatting will be performed.
         *
         * Pre-processing of searching data plug-ins - When you assign the sType
         * for a column (or have it automatically detected for you by DataTables
         * or a type detection plug-in), you will typically be using this for
         * custom sorting, but it can also be used to provide custom searching
         * by allowing you to pre-processing the data and returning the data in
         * the format that should be searched upon. This is done by adding
         * functions this object with a parameter name which matches the sType
         * for that target column. This is the corollary of <i>afnSortData</i>
         * for searching data.
         *
         * The functions defined take a single parameter:
         *
         *  1. `{*}` Data from the column cell to be prepared for searching
         *
         * Each function is expected to return:
         *
         * * `{string|null}` Formatted string that will be used for the searching.
         *
         *  @type object
         *  @default {}
         *
         *  @example

         *
         * The column type tells DataTables what ordering to apply to the table
         * when a column is sorted upon. The order for each type that is defined,
         * is defined by the functions available in this object.
         *
         * Each ordering option can be described by three properties added to
         * this object:
         *
         * * `{type}-pre` - Pre-formatting function
         * * `{type}-asc` - Ascending order function
         * * `{type}-desc` - Descending order function
         *
         * All three can be used together, only `{type}-pre` or only
         * `{type}-asc` and `{type}-desc` together. It is generally recommended
         * that only `{type}-pre` is used, as this provides the optimal
         * implementation in terms of speed, although the others are provided
         * for compatibility with existing Javascript sort functions.
         *
         * `{type}-pre`: Functions defined take a single parameter:
         *
         *  1. `{*}` Data from the column cell to be prepared for ordering
         *
         * And return:
         *
         * * `{*}` Data to be sorted upon
         *
         * `{type}-asc` and `{type}-desc`: Functions are typical Javascript sort
         * functions, taking two parameters:
         *
         *  1. `{*}` Data to compare to the second parameter
         *  2. `{*}` Data to compare to the first parameter
         *
         * And returning:
         *
         * * `{*}` Ordering match: <0 if first parameter should be sorted lower
         *   than the second parameter, ===0 if the two parameters are equal and
         *   >0 if the first parameter should be sorted height than the second
         *   parameter.
