Exodus Inspector: Add 'metadata' organization to 'block' widget
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Current PV (2.4) has some special logic in it to show 'material' and 'hierarchy views of the block structure. We need to move this to PV 3.0, though we need to think about the design of it. This is necessary for PV 3.0 at SNL.
