finding prime form

[Tobias Kunze]

i refuse to deal with (forte's) set theory and, hence, have no
idea what you mean by prime form.  surely not '(c4 c4), which
is the only musically meaningful definition of prime that comes
to my mind.

but sarcasm aside, if you'd give an example, i may have an algorithm
around somewhere.
