Subject: [PATCH] Measure time (#706)

* Create measure_time_elapsed.cpp

* add functionality to measure time elapsed of a code

* cout --> std:cout

* Update measure_time_elapsed.cpp

* Update time_elapsed.cpp

* Update measure_time_elapsed.cpp

* std:cout << getTimeInMicroseconds() - starttime;

* std:cout << getTimeInMicroseconds() - starttime;

* Update measure_time_elapsed.cpp

* Fix include order and use int64

* Remove trailing whitespace

* Delete time_elapsed.cpp

* int64_t

* #include <sys/time.h>

* long long

* int64

* int64_t

* __int64_t

* std::cout and std::nullptr

* #include <iostream>
