The TableFactory is a factory cacheing all Tables loaded by Vortex. All instances of Table have to be instanciated through the TableFactory. The factory keeps a cache of the Table instances which will be returned. If no chache exists a new instance of Table class is created, put into cache and returned.
Get a Table from the factory
$table = TableFactory::getTableFromName( 'myTable' );
Clear the factory cache (this you very seldom want to do)
