[tor-dev] Stem Integ tests for Tor

Hello! As part of the Stem Integ tests, nickm suggested integrating gcov into Stem. I did not get that part. Gcov is for code coverage of C/C++ source code. We could integrate it to Stem, but then it would involve executing command line statements on a gcov installed machine.

Also, we could add similar code coverage tool for Stem itself.

Did I get it right? How about adding coverage.py to Stem?
