Detailed Description

A MAMA source group monitors a set of MAMA sources that presumably provide a duplicate set of data.

Each member of the group is given a priority and the member with the highest priority is given the mamaSourceState, MAMA_SOURCE_STATE_OK; the other members of the group are given the state, MAMA_SOURCE_STATE_OFF.
