[cosmos-dev] Updated DMS code

[Marius Slavescu <slavescu@xxxxxxxxxx>]

I updated the TPTP DMS code to support
real RDB data sources for log and statistical schemas and also updated
the COSMOS testcases to provide a real data source to the data accessors.

Sheldon please update the reports to
use the same datasources as those in the testcases, the report should pass
a valid data source to the data accessors.
 
You'll need to retrieve from the web
application configuration file the URI (basically the parts of the URI
that are captured as constants in the tescase).

Thanks !
