// 32bit Random Generator using Kirkpatrick-Stoll(R250)
// 
// Call SetRandomSeed() before you use GetRandom() to get random numbers
// Use time counts as the parameter to SetRandomSeed() on win32 platform usually like this:
//	LARGE_INTEGER liCounter;
//	QueryPerformanceCounter( &liCounter );
//	CRandom.SetRandomSeed( (int)liCounter.LowPart );
