Created unit model with the name, utype, __unicode__method and status fields and registered the model in the admin
added tests, urls, views, and templates.

The tests are for two new urls, one which contains  a list view operator, and the other which inherits from that view. The urls display templates that grab data from the database using an operator. The UnitListView inherits the generic class based ListView.
