00025 /*      \class InputSystem
00026 
00027         An input system is the basic abstraction for an input API. You would
00028         want to have a specific input system for SDL, DirectX, Windows API, X,
00029         etc..
00030 
00031         The job of InputSystem is:
00032                 - Initialize the input API
00033                 - Initialize the inputcodes used in the InputServer
00034                 - Handle the creation of individual devices
