Implement find-method-combination

  • Store method combination as an object of type 'method-combination.
  • We use singleton objects if there are no options supplied to the method combination (the majority of cases), otherwise we cons up a fresh method-combination object with the same name that holds the options.
  • Property svn:eol-style set to native
  • Property svn:keywords set to Id
