//:PtMultiCallEvent contains PtCall-associated event data, 
//:where multiple calls are involved.
// MultiCall events are typically merges of multiple calls into a single call.
// The original set of calls may be retrieved via the getOldCalls method.  The
// new call that is generated, or the resulting merged call, may be retrieved 
// via the inherited getCall method.
