Detailed Description

Public class for exposing each of the registered creators through a selectable GUI component (in this case, only an OptionMenu is provided).

Creators are currently registered in the repositories constructor and added to the OptionMenu provided via the Initialise function.

Additional creators can be registered before an Initialise call (using the Register method), and Initialise can be called many times if necessary.
