I added Initialize() routines to Image, ImageAdaptor, ImageBase, ValarrayImageContainer and
ImportImageContainer.  The release data mechanism should now be operational for these base image
objects.
 
ReleaseData usage:
 
filter1 = SomeFilter::New();
filter2 = SomeOtherFilter::New();
 
filter1->ReleaseDataFlagOn();
 
filter2->SetInput( filter1->GetOutput());
filter2->Update();
 
filter1 will release its bulk data once filter2 has executed.  The assumption is that the buffer
between filter1 and filter2 is no longer necessary. If we then do
 
filter2->Modified();
filter2->Update();
 
filter1 will re-execute since its output was released after filter2 executed the first time.  So
filter1 needs to regenerate its output so filter2 can re-execute.  Again, after filter2 executes,
filter1 will release its output bulk data.
 
 
Todo:
 
1. Any other subclasses of ImageBase.  Does BloxImage need an Initialize? (Damion), what about
Histogram (?)
2. PointSet, Mesh need Initialize methods (Will)
