/**
 * 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](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-.

         *
         * * `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.

         * 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:
         *
