[Paraview] Setting a color map

[Reuter, Michael A.]

My current situation is that the user has already chosen an array to color
by. I'm then using the handy dialog box provided by the
pqColorPresetManager to allow the user to select a new colormap. I
retrieve the pqColorMapModel from the selection and then I want to apply
the new colormap to the current color array.

Cheers,
M
