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.

this completely doesn't make sense.  the pattern finds antecendens and anaphors that aren't nouns, and then throws these results away, and produces an answer that is a constant: two anchor nodes .  So, no matter what happens, this always returns the same answer !???
