add Package SQLAlchemy ORM model
Additionally, add an optional **kwargs passing via make_relationship.
This allows us to use things like uselist=False
, which was needed
for test/test_package.py.
NOTE As of this MR, we've got a new task: simplify models in general; we need to remove as many object deletions as possible, as setup_test_db now properly expunges records.
