• Remove IMP_SpellChecker::.

++ To discuss

• Refactor to remove all global variables and other couplings with global state ($_SESSION, $_REQUEST, singleton pattern, etc). We can do this by:

• Encapsulting request in a request object

• //Instantiate// master Horde object (e.g. {{$horde = new Horde($config);}})

• //Instantiate// application object (e.g. {{$app = new Turba($horde,$config);}})

• Page handling become method object (e.g. {{$page = new Turba_BrowsePage($app, $request); $page->execute();}})
