21      Responsible for putting together a user interface and data. In a typical 
22      scenario the user interface is made of widgets from a specific toolkit 
23      and data is retrieved from L{elisa.core.resource_manager.ResourceManager} 
24      in the form of L{elisa.core.components.model.Model}s. 
25      L{Controller}s are created by L{elisa.core.components.frontend.Frontend}s. 
26      Often, a notion of compatibility between controllers and frontends will 
27      exist. 
28   
29      Example: 
30   
31      A GTK based frontend will create a window and GTK specific controllers 
32      that in turn will create GTK widgets. The controllers will fill the 
33      widgets with the data of their choice.
