/**
* It can be quite useful to jump straight to a page which contains a certain
* piece of data (a user name for example). This plug-in provides exactly that
* ability, searching for a given data parameter from a given column and
* immediately shifting the paging of the table to jump to that point.
*
* If multiple data points match the requested data, the paging will be shifted
* to show the first instance. If there are no matches, the paging will not
* change.
*
* Note that unlike the core DataTables API methods, this plug-in will
* automatically call `dt-api draw()` to redraw the table with the current page
* shown.
*
* @name page.JumpToData()
* @summary Jump to a page by searching for data from a column
* @author [Allan Jardine](http://sprymedia.co.uk)
* @requires DataTables 1.10+
*
* @param {*} data Data to search for
* @param {integer} column Column index
* @returns {Api} DataTables API instance
*
* @example
* var table = $('#example').DataTable();
* table.page.jumpToData( 0, "Allan Jardine" );
