Add Parsing test harness for Odyssey case details

[zstumgoren]

Add a few initial tests, fixtures and basic parsing class for Odyssey case detail pages. Once the basics are in place, @justinmayo will run point on implementation starting with eviction case type.

We'll also need to consider a mechanism to dynamically load parsers based on case type, e.g. using a facade class that performs a preliminary check and returns appropriate parser class or a default.

Basic test module created and a few fixtures added for GA Dekalb. We can deal with dynamic loading of different parser classes when the need arises.
