Merge pull request #275 from RosettaCommons/JWLabonte/utilities
A few years back, I added what I consider a couple helpful convenience methods to vectorL. I had never written unit tests for them; now I have.
This merge also introduces a third convenience method for appending one vector into another, which would be really helpful for some sugar code I'm working on.
There is a simple carbohydrate code fix as a rider to this merge, so carbohydrate integration test changes are expected. All other tests pass.
