82    @class GUIManager
83    @brief
84        Provides a simple interface to CEGUI with tolua methods and console commands. It also acts as a key and mouse handler.
85
86        The GUIManager is a singleton and can be called anywhere when access on the GUI is needed.
87
88        Since the GUI needs user input, the GUIManager implements the functions needed to act as a key and/or mouse handler.
89        Those input events are then injected into CEGUI in Lua.
