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.

A question: why doe sureal take sentence fragments and complete them with
stuff found in the atomspace? Is this intentional, by design, or is this an
accident?
***

This is because it's incomplete, and I asked Amen to pause work on it for
October, to help make a PLN demo..

Right now (according to my possibly incorrect paraphrase of Ruiting's
verbal comments to me), sureal finds the SentenceNode that matches the
material to be verbalized, and then returns that SentenceNode, with
appropriate changes made to *parts* of it to make those parts match the
material being verbalized...

To fix this problem sureal should be dealing with PhraseNodes, not just
SentenceNodes....
