FIRST, the error "Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 32 bytes) in ....." is caused by parent::__construct()
I do parent::__construct() because I want the Controllers to have access to the Models, and with parent::__construct() you could do that, without doing
something like global $myController;, I guess you could also do myController::function, but I don't know.

Another thing that could be done is not load the classes on __construct(), but do some functions in the Bootstrap suchas as loadModel(), which would load
the Model class and all the Models, and use that function when we need to use the model(always in controller)

Example of that:

Class U_Controlller
{
public function login()
{
  $model = $this->loadModel() //Comes from the bootstrap

  if($model->U_Model->nameTaken($_POST['lusername']) == false)
  {
      echo 'Name is not taken!';
  }
  else
  {
      echo 'Name is taken!';
  }
}
}


Second, I am planning of calling the controller in the template files(.html) like {U_Controller-login}, by making each controller and its function a
template parameter, I do this in Controller.php, only problem is that when I set them as a param it calls the function, instead of calling it when the param
is read. Gotta' find a work-around to this.


Third, I am planning on doing something like, instead of $_POST['lusername'], do something like $Application->Controller->View->F_View->set();, which would
make  filtered($_POST['lusername']) into $Application->Controller->View->F_View->lusername; that's something I did for RevCMS.


Fourth, I am using an abstract database layer to handle which engine the CMS is using, I'm planning on implementing SQLite(maybe SQLite3), MySQLi, PDO_MySQL, MySQL,
PostgreSQL and MsSQL, since all these are very similar to MySQL, you could make it so they all use the same functions(connect, disconnect, query, get, clean)
and you could use any of them without having to edit so much, only problem is that some of them use the bind_param function so it requires some parameters in the
query and get(bind_result) function, but that isn't a mayor deal.

I don't know of anything else that needs work, at the moment it's rather an awesome but incomplete and needs-work BASE.
