ParseTree version 1.6.1 has been released!

ParseTree is a C extension (using RubyInline) that extracts the parse
tree for an entire class or a specific method and returns it as a
s-expression (aka sexp) using ruby's arrays, strings, symbols, and
integers.

Changes:

+ 2 minor enhancements:
+ Have been going insane on the tests, expect more soon.
+ Cleaned up using named nodes, now do: args = exp.scope.block.args(:delete).
+ 2 bug fixes:
+ Fixed #parse_tree to return superclass in :const node.
+ Fixed while/until with no bodies (now nil).
