This will require more additions to SuReal to see real working results (and for proper chunking), but the code logic should work.

As development is still on-going, some debug `display` messages are left in for now.

* Also worth considering whether using scheme is the best or not.
I thought the function was supposed to pattern-match with a sub-hyper-graph containing nodes of certain specifications, in this case, a PredicateNode "verb" among the r2l output, right?  But, the rest of the relex output is available in the atomspace, so wouldn't it be possible to pattern-match with the relevant sub-graphs of the relex output to find a verb, thus avoiding the confusion caused by using the r2l output? That's what I mean by looking for a verb. Or do I misunderstand what this piece of code is supposed to do?
