Xtend Test Coverage

[AtomCrafty]

I'm trying to determine the code coverage for my tests, but all of the results are relative to the generated Java code.
A preliminary search shows that it is supposed to be possible to show the coverage right in the Xtend source files, but all of these solutions appear to require intimate knowledge of the project setup that I don't possess.
@eyck could you take a look at this?

Possibly relevant:

Sure, I will check

Unfortunately this turns out to be not as straight forward as hoped. So we should post-pone to 2.1.
