  - fixed a bug in compatible-closure handling that could
    result in duplicate matches when there should only have
    been a single match.

  - added labels to edges for reductions
    when shown in GUI. See docs for
    reduction/name

  - small performance improvement to matcher 
    (10-20% on non-trivial examples)

  - added letrec.ss example (and improved some
    of the examples to use labels)
