- Update to new upstream release 1.63
* Corrections to methods for RightCoset and LeftCoset
* Removed HomsetCosetsGroupoidCoset + old IsHomsetCosetsType
* Operation RayElementsOfGroupoid is now Attribute RaysOfGroupoid
and Attribute RaysOfGroupoid is now Operation RayArrowsOfGroupoid.
* Changed HomsetCosets from IsPositionalObjectRep;
corrected SubgroupoidByPieces when rays are involved
* Add IsomorphismNewObjects method for hom discrete
methods for \in for AutomorphismGroupOfGroupoid
* Added property IsAutomorphismGroupOfGroupoidAsGroupoid
* Added method for \in for automorphisms of groupoids
