Superfluous behavior and non-DRY of calling classes through constructor too many times

Each App_Model class has these same lines:

include(APPPATH.'config/databases.php');
$this->base = $this->load->database($db['base'], TRUE); $this->granary = $this->load->database($db['granary'], TRUE);

This means App_Model, and Comp classes all load dbs. But those classes are never used on the ground. They are there for structure as basically abstract or skeleton-like classes.

Also, there is the whole repeating of those three lines for each App_Model (so repeated for every module). Should bump up the three lines to the Parent_App_Model class, but make it conditional so only Task children classes go through those lines. Parent_App_Model should NOT go through the lines itself.
