Tests!

[chaosphere2112]

Adds testing to CDMS. To run tests, execute python run_tests.py from the root directory. These will need a lot of cleaning up; the first 4-6 or so I exhaustively converted to "proper" unit tests, the last 20 or so I did not. On my machine, there are 5 failures and 2 errors.

Errors:

We're missing a DRS test file, which is why testDRS errors (the path used is just what was in the test_all_formats file when I got there). Not sure about the testHDF test; the file is there, but for whatever reason it isn't working to open it.

These all look like things @dnadeau4 and @doutriaux1 should figure out, not me.

[chaosphere2112]

Note: I'm going to be refactoring test_mv2.py and probably test_regrid2.py in order to use them to test the provenance capture as well.

[chaosphere2112]

Also, you can run any test file individually using python.

@dnadeau4 @doutriaux1 I'm totally ready for this to be merged now.
