Comments:
A simple class to demonstrate the use of DXDiagNVUtil which is a convenient wrapper for
the IDxDiagContainer interface from Microsoft.

GetGPUAndSystemInfo gets only a small fraction of the information that IDxDiagContainer
makes available.

Since this class is simple to create and destroy, there is no specific handling for when
the D3D device is lost.  Simply Free() and re Initialize() the class if that should happen.
