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.
OK, found it. William, please consider changing the one line 
```
(if (string=? (cog-name form) "_")
```
to 
```
(if (eq? (cog-type form) 'VariableNode)
```

This will make forms at quasi-compatible with the pattern matcher, and thus help avoid complexity if things change in the future...
