BaseContext - Base context class
The base context class is a context class all other context classes inherit from. Within ODABA two categories of context classes are provided:

- GUI context classes ( GUIBaseContext )
The base context class provides basic functionality for all context classes, e.g. supporting context hierarchies, executing actions, functions and programs etc.
