// Event_T class
//
// This module implements the Event_T class which is
// used by the Ace_T back end class to manage target events.
// When an event occurs, an Event_T event is created
// from the ACE event information, and the Event_T
// object is then put on the event queue.  When the
// target server requests information about an
// event, an Event_T object is dequeued.
//
// The Event_T constructor performs all the work for this class:
// it takes an ACE event and converts it into a WDB_EVT_DATA
// object, Wind River's event data type.
