Large number of failing tests on V2 master branch

[cmikida2]

Hi - I'm working with pyJac-V2 and have noticed that when I pull the master branch and run nosetests from the top directory, 25 of them fail (5 errors, 20 failures, and 3 skipped tests). Most of the failures are assertion errors, and hand-checking one of the simpler of these (test_set_concentrations) shows a legitimate failure of PyJac to return the same values as the reference answer. I'm wondering if this is the expected behavior for the unit tests as they exist currently on the branch. I've attached a full log of the output of nosetests.

I'm working with the latest commit to master (SLACKHA/pyJac-v2@1cdd67b). My loo-py version is 2018.1, installed via Conda, and I'm running the tests with nose v 1.3.7.

I'm happy to provide further clarifying information.
