Added initial dataset agent for CTDMO instrument.  Also fixed dsa
test_driver imports to use the dataset agent specific imports.  The
metadata now updates the versioned info correctly.
A few small changes to the parser and test driver.
Added repackaging and git versioning to package driver.
Merge branch 'ctdmo' of github.com:emilyhahn/marine-integrations into ctdmo
