Really? It depends on a specific DM implementation. If you offered up a
generic algebraic interface, then it could just be a normal explicit TS. But
it seems to me that DM is a better choice for particle tracking, at least
all the spatial queries and such.

Rationale: The function of characteristic is to handle the material derivative in a
timestepping method.

Caveats: I agree that the current implementation is dependent on DMDA. This
should be remedied.
