alex mcadams 08d4c21e25 Softs Evolution with linear system solver. ...

Currently only XPBD springs, gravity, and collision proximity forces are supported. Very experimental.

This uses Eigen for the linear solve. No optimization has been done to make building the matrix efficient. Mostly for testing right now as it's super slow and not particularly stable!

Also updated XPBD spring stiffness and damping to be actually resolution independent now that I actually have a ground truth. XPBD has weird approximations that make it so tuning it to be resolution independent is an unknown problem, so whatever I had done before wasn't actually correct or generalizable.
