Change comparison level for isomorphic_species_list in KineticsFamily

Change to level 2 (InChI comparison) for speed in
  __createReaction (to check that reactants and products are different)
  __generateReactions (to match the specified products)
  getLabeledReactantsAndProducts (to match the specified products)
