AMDS Data Store

I checked in the first batch of database definitions for the AMDS Data Store to SVN. This is basically the DDL for all the tables, views, triggers, etc. that we're using for the AMDS Store that will be populated with, initially, synthetic BioSense data. This will help out anyone else who is looking to build their own aggregate store.

I'm also starting a list of conditions and classifiers that we'll use internall in the AMDS Store but will be useful to any others developing AMDS services.

Eventually this will have DDL for postgres, any other dbs we can create scripts for by request.
