Microplanning v0.01

Currently for "declarative" sentences; see the included formatted README.md for more detailed information.

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.
The initial purpose was that, given a set of hypergraphs (different links all in R2L style output) given by the action planner, I want to determine which one can form a sentence without other supporting graph (so that subsequently I can slowly add more links to form longer sentence).  In this case I have chosen the structure of SV, SVO, and SVIO rule.

Just determine which graph contains a "verb" is possible, but will not be able to help me determine if it is a complete sentence.

Unless of course, we re-design the microplanner to not require such a step... but given the way SuReal is designed, I am not sure this step is avoidable.
