v.1.0.7

* rank/unrank involutions in swap order (not very efficient)
* generation of involutions in reverse not implemented yet
* rename some static methods (eg gray -> toGray,fromGray)
* Permutation.initial generate kfixed derangements and kcycle permutations, although they are to be generated by combining other iterators
