Project autoplot-test037

run scripts found in scripts/test037, check that results haven't changed.  The tests that start with [a-z] are run.  The goal here is to provide an easy method to create tests, where users of the software can create arbitrary tests, and ultimately a method where people can submit tests for nightly testing.  Artifacts starting with "test" and ending with ".txt" and ".png" are archived.
