* dxSystem
* Simon GL Jordan 

* Description:
* The main workhorse of the directX to Windows interface in the engine.
* Handles safe construction and deletion of DirectX resources.
* 
* Use:
* All main elements are included here, dxSystem pieces together parts of the engine.
* All rendering and processing is done here of other engine elements, before being
* parsed into winMain
*
* Future Implementations:
* 1. Input system
* 2.System timer
* 3.System resources analysis(memory, disk space)
