Working index write planning and reference implementation in `InMemoryAdapter`, which now appropriately extends `IndexedModelAdapter`.
Massive Model API cleanup. `InMemoryAdapter` support for indexed fields. Restructured testsuite dispatch and loader structure to avoid duplicate test runs. Fixed over 30 bugs in the model API, added over 40 new tests and achieved 100% test coverage for the model core (`apptools.model`). Full support for `ModelMixin`/`KeyMixin`, models now support Python's Item API (obj[prop]), support for queries stubbed and coming soon.
Quick bugfix for testrunner.
Added model adapter tests to testsuite.
Tweaks to Model API to conform to ProtoRPC services, improvements/bugfixes in service layer.
First revision of a full exception infrastructure for the Model API.
Tweaks and improved commenting for the Model API and RedisAdapter.
