Detailed Description

Simple group implementation that allows arbitrary strings as group names.

However, the group names must use a string representation of the local node ID as prefix. Each group instance spins up an intermediary actor to enable remote access to the group. The default module is used internally by the "local" as well as the "remote" module.
