@cbolisetti I believe this can be closed due to #14658. Can you confirm?
Yes, we can close that!

Reason
An explicit time integrator will help in solving highly nonlinear dynamics problems, as well as mechanics problems involving shock loads.
Design
Adding a centraldifference time integrator, which will derive from the ActuallyExplicitEuler class. This timeintegrator will calculate udot and udotdot according to the central difference equations. Inertiakernels in tensormechanics will be changed to automatically use udot and udotdot from the timeintegrator, so that the input doesnt have to be changed when users use explicit integration instead of implicit.
Impact
Minimal impact on everything else. This is an added feature.
