$filters = new Bvb_Grid_Filters();
$filters->addFilter('field',array('calback'=>'my_callback_function','params'=>array('optional','params')));

If you print_r() your func_get_args();

you will see somehting like this by default:

array[0]
            ['field'] => 'the field that is being filtered'
            ['value']=>'the value to filter'
            ['select']=>The select instance. YOU are responsable for apply the filters usign the provided select instance
            
            
If you pass any optional argument with $filters->addFilter() they will be merged.
