The treatment of accretion in #79 caused some trouble when the accreting particle reaches coarse regions. In order to maintain resolution, I now treat the accretion radius in the same way as the gravity softening radius where it is guaranteed to resolve the accretion with at least a few cells. There may be some unforeseen physical implications.
