Regridding between coarse grid time steps? #51

Figure out how to regrid between coarsest level time steps. Right now, I only regrid when the coarsest level has been updated. Doing it in between steps could be interesting....

Original comment by Carsten Burstedde (Bitbucket: cburstedde, GitHub: cburstedde):

I agree. Another way of putting it, whenever we have completed a step on level 2**(-L), we may regrid in a way that only levels L and up (finer) may change (no coarsening below L). Would this be desirable?

If yes, I'd have to think about a p4est function that does this. It may be too involved for the near term.
