MILETONE: the rhythmmakertools package now contains the correct number of
classes. RhyhmMaker is the abstract base class from which all other classes in
the package inherit. There are eight concrete classes. All concrete classes
inherit from RhythmMaker and only from RhythmMaker; importantly, no concrete
classes inherit from each other; the depth of the package class hierarchy is
only 2 (when measured from RhythmMaker).
