  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.]
