// Description:
//	This file declares the CDiskView class.  This class gets several properties
//  from a Win32_LogicalDisk instance and displays them.  
//
//  A barchart of the free and used disk space is shown on the left and an 
//  edit box on the right displays several other properties such as the object
//  path, filesystem type, etc.
