Starting CC3D again~

added contact plugin from cell behaviors and properties
specified adhesion energies
updating attributes
parentCell.targetVolume/=2 (every time cell divides, volume will be
decreased by half)
temperature = 0.1 (cells look better. highest i would go is 10)
In paper, radius = 40 and width = 5
note: cells are not starting at 1, but 193. (not sure why)
If you want to add a steppable, right click underneath the CC3D
simulation and python and click "add steppable"

I think that is the most of what I changed. The code is not working
right now, not sure why, but I am going to keep playing with it to
figure out why. But for now, we have stem and nonstem showing in the
simulation rather than the border.
