Bumped to version 1.1.0

 - GraphISO_furer.py and furer graphs added
 
 - createPath() function added to pyCTQW.MPI.io
 
 - ismorphicQ() gains the ability to save certificates
   and accept certificates as input in addition to
   adjacency matrices
   
 - AllIsomorphicQ() saves certificates rather than
   recalculating them, becoming more efficient
