Tests for the diagnostic system, run with:

[nichannah]

    $ py.test

Or if you don't have py.test installed:
$ python tests/runtests.py
Asl use --help, paying particular attention to the 'custom options' section.
See CommerceGov/NOAA-GFDL-MOM6/#147.

This pull request includes:

• tests for diagnostic output. These tests are generalized to run on any experiment.
• infrastructure for the above, this will make it easier to make Python based tests in the future.
• a script dump_all_diagnostics.py which can be used to dump all the diagnostics for a particular test case/experiment.
• a thing called runtests.py which is a stand-alone version of py.test - so people can run the tests without needing to install py.test.

I moved this from MOM-examples/tests to MOM_examples/tools/tests.

@nicjhan I'm having some issues with dump_all_diagnostics.py (see below). What directory should the script be invoked from? If you look at the path that is being constructed, it's insert "lustre" between "MOM6-examples" and "diag_table".

BTW, Can you post results fomr "module list" for the environment that you used to run the tests. I think there are some dependencies we need to document...

[nichannah]

OK, it looks like I've made some bad assumptions. I'll take a look at it now and get back to you.
