Social groups

The social groups are the primary areas (circles) where social interactions occur.

Social groups have resemblance to Facebook groups.
Unlike FB groups, social posts are always grouped. There is no personal space, unless a personal group is defined.

Important attributes:

Code - this is the unique code of the group. It is also used as a slug which forms part of the URL for the group, posts, etc.
Name - the universal name of the group.
