Gaussian starting, periodicization
implemented Gaussian starting strategy for minimization
much-improved bloch visualization, better interactivity
periodicization of Bloch functions, checking, saving of these
improved verify_bcs to check periodicized functions
improved verify_orthogonality to check periodicized functions
actually *use* periodic Bloch functions for minimization, not 
  regular Bloch modes as before
code cleanup in photonic_crystal.py
