So - not knowing about FCC's - there is the possibility that these Flux Control
Coefficients can _already_ be interpreted as having units of bits!  Two
questions come up: what exactly is a FCC (besides Frederick Community College)
and whether one can interpret them as measuring some kind of choice being made
by the system.
