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:

+ 1 minor enhancement:
	Switched short if/unless to 1 line expressions.
+ 2 bug fixes:
	Fixed the nested case/when bug. YAY!
	Added dasgn_curr and defn_rescue test cases.
