Gtest

Add unit testing to wolf with googletest.

If the BUILD_TESTS option is enable in the top level CMakeLists.txt it will retrieve googletest from github and compiles it.

Then all wolf-tests present in the test folder are compiled in one single executable. This executable can be break-down into smaller chunks - see test/CMakeLists.txt

Provide a very simple test as an example.
