Description

The idea here is to build a parser that can get implied relationships from resource maps as well as the explicitly stated ones.

Performance-wise, try to limit what the model parses to what is being looked for, (not extraneous definitions submitters may choose to add) so that memory and computation time are limited.

determined how to build the parser, and added boolean for specifying a reasoning parser.
The reasoning parser uses more memory than standard one, so should be used judiciously.

As thought expermiment, I was able to make the aggregates predicate transitive by altering the ORE terms definitions. This would be to be able to make inferences about aggregates of aggregates. Included the files here for reference - they are not implemented. The idea is that these would be read into the reasoning model to get the behavior desired. (if A aggregates B, and B aggregates C, then A aggregates C, through inference)

Hi Rob - it looks like this work is complete. Can this work be moved to the release branch so we can begin testing the 1.2.2 release in preparation for tagging.
