/**

 * When DataTables removes columns from the display (bVisible or fnSetColumnVis)

 * it removes these elements from the DOM, effecting the index value for the

 * column positions. This function converts the visible column index into a data

 * column index (i.e. all columns regardless of visibility).

 *

 * DataTables 1.10+ has this ability built-in through the

 * `dt-api column.index()` method. As such this method is marked deprecated, but

 * is available for use with legacy version of DataTables.

 *

 *  @name fnVisibleToColumnIndex

 *  @summary Convert a column visible index to a data index.

 *  @author [Allan Jardine](http://sprymedia.co.uk)

 *  @deprecated

 *

 *  @param {integer} iMatch Column data index to convert to data index

 *  @returns {integer} Visible column index

 *

 *  @example

 *    var table = $('#example').dataTable( {

 *      aoColumnDefs: [

 *        { bVisible: false, aTargets: [1] }

 *      ]

 *    } );

 *

 *    // This will show 2

 *    alert( 'Visible Column 1 data index: '+table.fnVisibleToColumnIndex(1) );
