  ##
  # Parse source string and return a Abstract Syntax Tree (AST) of the source.
  # You may also pass in additional options to affect the reported filename
  # and which version of Ruby you want to use:
  # 
  # === Parameters
  # * _source_string_ source you want to parse
  # * _opts_ customize how your source is parsed (:filename, and :version [defaults to 1.9])
  # === Example
  # JRubyParser.parse(%q{puts "hello world"}, :version => JRubyParser::Compat::RUBY1_8)
  #
