	To create new module:
	
		#define MODULE_EXPORTS
		#include "ModuleIface.h"
		extern "C"{ 
				MODULE_API int calcfunc(const char* inputDataStr, CalcControl* control)
				{ 
					//Place your calculation code here
						// "inputDataStr" variable contains input data string.
						// "control"- call "control->isInterrupted()" to check if it needs to stop calculations.
						// 	      "control->setResult() to return result after calculation.
					
				}
