 		 * (parameters described below) that is called for every row in the table,
 		 * and your logic decides if it should be included in the searching data set
 		 * or not.
 		 *
 		 * Searching functions have the following input parameters:
 		 *
 		 * 1. `{object}` DataTables settings object: see
 		 *    {@link DataTable.models.oSettings}
 		 * 2. `{array|object}` Data for the row to be processed (same as the
 		 *    original format that was passed in as the data source, or an array
 		 *    from a DOM data source
 		 * 3. `{int}` Row index ({@link DataTable.models.oSettings.aoData}), which
 		 *    can be useful to retrieve the `TR` element if you need DOM interaction.
 		 *
 		 * And the following return is expected:
 		 *
 		 * * {boolean} Include the row in the searched result set (true) or not
 		 *   (false)
 		 *
 		 * Note that as with the main search ability in DataTables, technically this
 		 * is "filtering", since it is subtractive. However, for consistency in
 		 * naming we call it searching here.

 		 *  @type array
 		 *  @default []

 		 * 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
 		 *
 		 * Each function is expected to return an array:
 		 *
 		 * * `{array}` Data for the column to be ordering upon
 		 *
 		 *  @type array
 		 *
 		 *  @example
 		 *    // Ordering using `input` node values
 		 *    $.fn.dataTable.ext.order['dom-text'] = function  ( settings, col )
 		 *    {
 		 *      return this.api().column( col, {order:'index'} ).nodes().map( function ( td, i ) {
 		 *        return $('input', td).val();
 		 *      } );

 			 *

 			 *
 			 * `{type}-pre`: Functions defined take a single parameter:

 			 * And return:

 		     *  2. `{*}` Data to compare to the first parameter

 	/**
 	 * 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

 		 * 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](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.
 		 *
 		 * * `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

 		 * * `string` - read an object property from the data source. There are

 		 *   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

 		 * * `object` - use different data for the different data types requested by

 	 * * `moment` - Uses the MomentJS library to convert from a given format into another.
 	 * This renderer has three overloads:
 	 *   * 1 parameter:
 	 *     * `string` - Format to convert to (assumes input is ISO8601 and locale is `en`)
 	 *   * 2 parameters:
 	 *     * `string` - Format to convert from
 	 *     * `string` - Format to convert to. Assumes `en` locale
 	 *   * 3 parameters:
 	 *     * `string` - Format to convert from
 	 *     * `string` - Format to convert to
 	 *     * `string` - Locale
 	 * * `number` - Will format numeric data (defined by `columns.data`) for
 	 *   display, retaining the original unformatted data for sorting and filtering.
 	 *   It takes 5 parameters:
 	 *   * `string` - Thousands grouping separator
 	 *   * `string` - Decimal point indicator
 	 *   * `integer` - Number of decimal points to show
 	 *   * `string` (optional) - Prefix.
 	 *   * `string` (optional) - Postfix (/suffix).
 	 * * `text` - Escape HTML to help prevent XSS attacks. It has no optional
 	 *   parameters.
 	 *
 	 * @example
