New description:
This patch begins the process of creating a convenient place to locate
examples of groups, much as is the case for graphs, digraphs and posets.
It creates an object and populates it with methods that return groups.
For general families, it just employs the class where the group is
implemented, such as for the Mathieu groups. For more specific (simple)
examples, the group may be implemented in the method, such as for the
quaternion group expressed as a matrix group.
Naming decisions were made to maximize the effectiveness of tab-
completion. Once the infrastructure is in place I will work to add
'''every''' possible example implemented in Sage.
'''Apply:'''

Comment:
Substantially reworked now with modules and imports doing all the work.
Top-level "groups.<tab>" object with primary divisions by implementation
(such as groups.permutation.<tab>).
Previous patch has lots of documentation that could go to help some of
these files, it needs it. On another patch, later.
Previous patch had an initial foray into manufacturing some sporadic
simple groups. On another patch, later.
v4 patch is ready for review now.
