> Some of the webapp tests fail because of dependency on catalog project. It is unable
to start the jetty server, as it can't find the Catalog classes. 
> Catalog project is hard-coded to generate Gremlin that is specific to Tinker Pop 2. 
It needs to be updated to use GremlinExpressionFactory to generate Gremlin that is appropriate
for the version of Titan being used.  In addition, it has direct dependencies on titan 0 /
Tinker Pop 2 classes.
