Lib Sub-System: Group

The group sub-system enables a process to become sequential consistent with other ones and communicate as a subgroup with other subgroups.
As long as at least one member of a subgroup runs, the process the subgroup represents continues to run.

The configuration of the group must be set at creation of the group and can not be changed during runtime.

The process of creating and joining a group is:

Create a group object
Configure (at least one) local server
Configure all members (always in the same order)
Configure any connections to the members
Activate the group
(Optionally) Receive recovered state data from another subgroup member
Accept local presence in the group
