/** \class plCoopCoordinator
    Manages cooperation betweeen several generic brains; primarily serves as a place
    to send synchronization messages. Originally this was going to be the role of the
    'host' brain, but that didn't provide a good interface point for Python.
    This object can either be a "helper" for Python, or its functionality can be
    recoded in Python.
