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.

when I say "the old way" I mean using (ReferenceLink (VariableNode "$word-inst-antecedent") (VariableNode "$word-inst-anaphor"))  instead of generating the constant (ListLink  (AnchorNode "CurrentResult")  (AnchorNode "Filtered"))
