/**
* 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.
