#7 All tentatively tested ArgoUMLDelete2, JHotDrawTransform,
JHotDrawSelect2 traces etc.

isCreation() is true.

 Creates edge when executing static method.

For objects returned by Collections.unmodifiable(), List.iterator(),
etc., set the flag to true in Reference.isCreation() generated in
method.

Modify createObjectVertices() to generate ObjectVertex of coordinator
when both srcSide and dstSide do not include a coordinator.Change to
generate calling methodExec in doAnimation() when the beginning was
RECEIVER .

Add curved edge drawing when 3control points on the side.
Change occurrencePoint.getMethodExecution().getSignature() in
Alias.getMethodSignature().

#5 Fix DeltaViewer#doLastAnimation() to remove Argument,
Local when method execution finished<pre_Exp1,2>.

Tidy up DeltaViewerSample.java and Adjustment when static class methods.

#5 Change DeltaViewer#removeMethodExecutionVertex() to remove Argument,
Local whend method execution finished.

Change DeltaViewerSample#createObjectVertexOnConstructor() so that the
sourceCell refers to the absolute position.
Implemented DeltaViewerSample#createObjectReference()
for Collection.

MethodExecutionVertex when resize ObjectVertex #3.
