/** >Utility
		This class is only available to OriginPro users. 

		The Profiler class can be used to measure various function calls to identify the slower functions

	Example:
		#include <origin.h>
		#include <profiler.h>
		void test()
		{
			Profiler tempObj; // just need to place this as 1st line in function
			
			INIFile nlsf_ini(GetAppPath() + "nlsf.ini");
			Tree trTemp;
			if(tree_read_ini(trTemp, nlsf_ini))
				tree_dump(trTemp, "nlsf.ini", WRITE_COMPILER_OUTPUT);
		}
