DONE:

Port to new VTK
1) scalar bar now works again. It had disappeared.
2) Fixed window interactor. For some reason a header file is not installed in the new versions of VTK. Reported this as a bug to VTK.
3) getRange now takes different parameters than before
4) Made save to images in popular formats (PNG,JPEG, and PS)

New Functionality
1) Previous button added, now you can go backwards through timesteps.
2) Made save to images with higher resolution than just the display. Currently this is hardcoded to 4x, but I'd like to make that a parameter.
3) Checkboxes to enable/disable each chunk
4) Ability to hide the scalar bar.
5) Reset Camera Button, will zoom to viewable.
6) Add labels for nodes / elements
7) Can display wireframe as tubes with spheres on each point
8) Disabling of next/prev buttons when they are not appropriate
9) Inverting of color schemes(text & background)

Bug Fixes
1) Won't crash on going past final timestep
2) wont crash if different numbers of chunks exist for different timesteps



TODO:

Ability to view only "valid" elements. Now our framework can contain holes in its data arrays corresponding to invalid elements.

Delete all actors and props appropriately. Currently little cleanup has been coded.

Flexibility in color schemes, currently only black background is allowed.

Make it quit gracefully when selecting quit from menu. Ctrl-C is not elegant.

Allow spaces in filename to full NetFEM path

Make labels correspond to a user attribute
