First cut of contact enforcement by using DBCs.

Seems to work, but need to check materials properties for copper.

Not truly accurate because of log strains, but
serves as a guard against code breakeage.
Pair programming with Brandon

@lxmota Have you been able to re-try the critical time step estimate?

I haven't yet, but only because I haven't had the time! Brandon and I got the contact working yesterday and got some preliminary results! We think some of the material properties for the hardening law that I was using were off, so we need to rerun with better properties, but we could see the contact, and recoil and some plastic deformation. I'll send out a movie separately.
