This adds the Boost μt unit testing framework to the codebase.
This is a header-only freely redistributable framework which encapsulates most different unit testing styles (suites, rspec, gherkin). For the tests here, I am using the most simple 'suites' style, but we could use other styles as well.
The overall engine however, is not very amenable to unit testing in it's current state. I have provided some examples of testing various functions within the faction and unit classes, in order to provide some guidance on how tests might be written, but writing thorough tests will be hard without refactoring a lot of the current engine framework. That is something I believe should be undertaken over time however.
