Description

- Add a mag(velocity)*dt velocity increment to the RCB used in redecomp (if not already done), the grid search, and the interpenetration length scale used in the CG filtering.
- This will help us not miss contact for two objects moving very fast toward one another with a relatively large dt.
- Ideally, this will help Tribol not miss the contact and compute a suitable timestep to catch the contact in the next contacting cycle (i.e. we catch contact candidates that are quite far apart, but moving toward one another very quickly with a large dt).
