Useage :
- Link action to key :
Input::LinkActionToKey(ACTION_TYPE Action, struct Key Button);
Input::UnlinkAction(ACTION_TYPE Action);
- Query action directly :
Input::GetStatus(ACTION_TYPE Action);
Input::WasPressed(ACTION_TYPE Action);
Input::WasReleased(ACTION_TYPE Action);

Also works with raw button, but not advised :
Input::GetStatus(Key Button);
Input::WasPressed(Key Button);
Input::WasReleased(Key Button);
