Scripting atom color changes as a function of velocity in Blender

Atom colors change as a function of their velocity using the basic how-hard-is-it-raining convention, slower is blue, white is pouring. RGB values for individual atoms were calculated from molecular dynamics data and imported as object color IPO curves. For this I expanded Miron's import IPO script to include three more curves, one for each RGB.

I plan to develop this more to represent temperatures.
