Implementation of modified version of hobbs algorithm

@linas  It's still in progress, but it can do some basic resolutions right now, see Readme file for details.

It would be better there was some some sort of unit test that could automatically run this. (And thus this file should eventually move to the /tests hierarchy (/tests/nlp/anaphora))

If you don't need any agents or python for the unit test, then some example unit test can be found in /tests/scm  Examples using the pattern matcher are in /tests/query and so maybe /tests/query/EinsteinUTest is the closes to what you do here.

If you have to also have python & agents, then look for examples in the /tests/python directory.   It be great if this was at least partly unit-tested before the end of summer.

This dataset is at the maximum size of what we should allow into opencog ... If you want to save anything larger, do it in https://github.com/opencog/test-datasets
