Adds the Simion-Schmidt map to the permutation class.
This map implements the Simion-Schmidt map which sends an arbitrary
permutation to a pattern avoiding permutation, where the permutation
pattern is one of four length-three patterns. This method also implements
the bijection between (for example) ``[1,2,3]``- and ``[2,3,1]``-avoiding
permutations.
