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.
Some of these maybe OK to move to utilities.scm or nlp-utils.scm eventually.  Though everything is still global.

I was trying to make it more modular by use the Scheme module thing Linas mentioned, but it seems once I wrap a file in a module, it cuts off access to OpenCog scheme...  (ie. I can't do `(ConceptNode "test")` to create a node)  Still trying to figure it out.
