Memo Atken's precise timer class from MSALibs but with Windows support
Uses Windows API QueryPerformanceCounter: http://msdn.microsoft.com/en-us/library/windows/desktop/ms644905(v=vs.85).aspx
QueryPerformanceCounter retrieves the frequency of the high-resolution performance counter, if one exists. If the installed hardware supports a high-resolution performance counter, the return value is nonzero.
