Basics done
experiments with part 2 - partials, defaults, match
added implementation of times, makeOrderedLeafList
Part 2 looks fine
decode seems to work fine
encode works fine, fixed singleton tests
part 4 is complete. High time to submit.
scala style problem fixed (9.92). Method name should not start with small letter. However my functions were kind of constants. Maybe write val ALWAYS = thePrivateAlwaysFunction
