v.2.0.0, contd

* Expr asin,acos,atan,asinh,acosh,atanh derivatives

v.1.0.8

* typo fix

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

v.1.0.6 in progress

* make sure rank methods rank valid objects
* some more static methods split in two eg toGray, fromGray

v.1.0.5

* update examplea and tests

v.1.0.0 contd
