25 * Lifeline is the UML2 lifeline graphical representation.<br>
26 * Each lifeline owns a set of event occurrences. An event occurrence is the base element in UML2 to set an event in a
27 * sequence diagram.<br>
28 * Event occurrence define the drawing order of graph node along a lifeline. In this lifeline implementation, event
29 * occurrences are just integer index. The event occurrences with the same value on different lifelines will correspond
