//:The <CODE>MultiCallMetaEvent</CODE> interface is the base interface for
// all multiple-call Call Meta events (multi-call MetaEvent).
// All multi-call MetaEvent's must extend this interface.
// Events which extend this interface are reported via the
// <CODE>CallListener</CODE> interface.
// <p>
// An individual <CODE>MultiCallMetaEvent</CODE>
// conveys, directly and with necessary details,
// what an application needs to know to respond to
// a multiple-call higher-level call event.
// The specific MultiCallMetaEvent event is indicated by
// the <CODE>Event.getID()</CODE>
// value returned by the event.
// <p>
// The core package defines events which are reported when
// high-level actions occur. The event IDs
// (as returned by <CODE>Event.getID()</CODE>) are:
// <CODE>MULTICALL_META_MERGE_STARTED</CODE>,
// <CODE>MULTICALL_META_MERGE_ENDED</CODE>,
// <CODE>MULTICALL_META_TRANSFER_STARTED</CODE> and
// <CODE>MULTICALL_META_TRANSFER_ENDED</CODE>.
