Added test_case related to anonymous namespace.

[bveldhoen]

Added a unit test to try and reproduce a suspected issue. I'm running into a problem when executing tests. What am I doing wrong?

@bveldhoen Thanks for the PR.

First of all, please note that there is already a test case for anonymous namespace:
https://github.com/bkryza/clang-uml/blob/master/docs/test_cases/t00015.md

Also your new test case does not crash or fail - my suspicion was that you had an anonymous namespace in the root namespace?

As to the issue with running the test cases on your system, the error says:

LLVM ERROR: Cannot chdir into "/home/bramv/src/projects/clang-uml/debug/tests"!

Could it be a permissions issue?

in any case - can you try make test and see if that works?

Abandoning because this scenario is already covered.

I suspect the error has something to do with installed clang versions. On another machine, I didn't get this error while running the tests (without modifications). Also, on the machine on which I was getting the error, I needed to specifically use clang-cpp12 in order to get it to build (see change to CMakeLists.txt file in this PR). I probably need to compare the differences in installed clang packages on both machines. Will do so when I have the time.
