 * Class:   EventDistributorRoot
 * Author:  dlemmerm
 * Date:    5/31/03
 * Purpose: This class is responsible for reading GLUE events from normal sources,
 *          (e.g. VRPN), packing these into a buffer, then when the Client nodes
 *          are ready to process this buffer, this class broadcasts the packed
 *          buffer and continues to pack new events.
