/**

 * 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.
