Synopsis [Reads in the supergate library and prepares it for use.]
Description [The supergates library comes in a .super file. This file
contains descriptions of supergates along with some relevant information.
This procedure reads the supergate file, canonicizes the supergates,
and constructs an additional lookup table, which can be used to map
truth tables of the cuts into the pair (phase, supergate). The phase
indicates how the current truth table should be phase assigned to
match the canonical form of the supergate. The resulting phase is the
bitwise EXOR of the phase needed to canonicize the supergate and the
phase needed to transform the truth table into its canonical form.]
