1. (Re)wrote the way in which programs are started in DataHives.
2. Wrote a simple (triple counting) program for the updated DH infrastructure.

* [DH,SC] Removed old code (associated with the old way of starting a DH program).
* [DH_NETWORK,SC] Module renamed.
* [DH_NETWORK,O] Adding connections between graphs is now faster since we use the smallest of two RDF graphs to steer the matching process.
* [DH_NETWORK,FIX] Triple name would not show in state_display/2 and found a typo which refers to a very different (once upon a time) product.
* [DH_PROGRAM,SC] Module renamed.
* [DH_PROGRAM,NEW] Complete rewrite of the way in which a program / multiple programs are started in DataHives.
* [DH_TEST,SC] Updates to reflect the new way of starting programs in DH.
* [DH_TRAVERSAL,SC] New module, taking predicates from DH_SAMP.
* [TRIPLE_COUNT,NEW] New module, implementing a DH program, loosely based on some existing predicates.
