/**
 * Remove all filtering that has been applied to a DataTable, be it column
 * based filtering or global filtering.
 *
 * DataTables 1.10+ new API can achieve the same effect as this plug-in, without
 * the requirement for plug-ins using the following chaining:
 *
 * ```js
 * var table = $('#example').DataTable();
 * table
 *   .search( '' )
 *   .columns().search( '' )
 *   .draw();
 * ```
 *
 * Please use the new API in DataTables 1.10+ is you are able to do so.
