[Paraview] Automatically scale color map

[Alex Lindsay]

Ken & Cory, thank you both for the input. I agree that changing scales 
can be very misleading! However, at this point I'm investigating some 
very new physics that I don't quite have an intuitive grasp of yet. 
Thus, being able to see the max and/or min in the domain and its 
location evolve over time is useful for me. Cory's suggestion works well 
for this.

Thanks again guys!
