/**
 * Creates `rowspan` cells in a column when there are two or more cells in a 
 * row with the same content, effectively grouping them together visually. 
 * 
 * **Note** - this plug-in currently only operates correctly with 
 * **server-side processing**.
 *
 *  @name fnFakeRowspan
 *  @summary Create a rowspan for cells which share data
 *  @author Fredrik Wendel
 *
 *  @param {interger} iColumn Column index to have row span
 *  @param {boolean} [bCaseSensitive=true] If the data check should be case
 *    sensitive or not.
 *  @returns {jQuery} jQuery instance
 *
 *  @example
 *    $('#example').dataTable().fnFakeRowspan(3);
