Comment:
Patch contains a new class, {{{OperationTable}}}.
This is meant for educational applications, and is unlikely to be used for
anything much bigger than can be displayed on a screen or a sheet of
paper. So the speed (it is a bit slow) is not a concern.
Since it only requires a binary operation, I created the groupoids
directory, based on the existence of a category by the same name.
Next thing will be an application of this class to generic groups, fixing
#7340. There are stubs left here for methods to create color and
grayscale graphics of the tables.
