[ISSUE 632] Graph Manager Unit Tests

[Oelgazz]

closes #632

[Oelgazz]

Currently 4 of the Graph Manager's tests fail. This is because of the Parameter Manager's dependency that is outlined in issue #634 . These tests will pass once that issue has been fixed.

We indent to 3 spaces in our code base. I recommend adjusting the indentation spaces in your IDE or our clang-format check will fail.

I know that most of the methods in the GraphManager class are thin wrappers around the Boost Graph Library but it might be a good idea to write tests for them. One could still make mistakes and break functionality. These tests would serve as a check against breaking functionality and also demonstrate how the GraphManager works.

The GraphManagerTests.cpp file doesn't pass the clang-format check because it uses the Windows-style end-of-line characters (\r\n) at the end of each line, instead of the Linux one (\n ). If you open the file with vim -b you will see a ^M character at the end of each line, which is how \r is rendered.

You must convert that file to the Linux end-of-line character (\n).
