Random color filter
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
We need a filter that will paint cells by random colors. This is different than the new catigorical color code.
An example would be to paint disk_out_ref.exo by GlobalElementId.
For this bug, lets make the filter dumb. In other words, don't worry about cells that end up the same color next to each other (that are not in contiguous GlobalElementId order).
An example of what I want is shown by creating a random number in the calculator. It is part of my tutorials here: http://www.paraview.org/Wiki/Beginning_Filters#Calculator_filter
