nothing works, but spec files created and reservation_spec has a lot of pending tests
 EquipmentModel factory acting very strangely but other factories debugged(?)
small edits; determined that EquipmentModel is the source of the bug but still no idea why
first group of tests
reinstalled rspec, reservation_spec working, wrote 'when valid' specs
small edits to reservations spec, added cart reservations spec and factory
added 'when empty' context to cart_reservations
actually added cart reservation spec to commit (?), added cart bad date specs
more validations checks in cart res spec; some have to be commented out
reservation spec contexts with bad dates and with no equipment model
reservation spec context 'with no user' added
overdue reservation context in reservations spec
updated black out factory, added context 'with blackouts' to res spec
added sequencing to factories, created 'available' test
added quantity validation tests
everything but scopes tested
Merged factories & tests from #366 branch
