[Paraview] [EXTERNAL] Assign colors to brain fibers

[Moreland, Kenneth]

You mean you want to save the geometry with the colors attached?  When you
save the geometry, the id for each line is saved, but not the color
associated with each id.  You can get the colors back by coloring by the
ids again when you reload.
