Unclear error message when max_ode_step is too large #1

I get this error:

cppad-20130918 error from a known source:

It would be helpful to say that ode_step = 2 is probably too large, and even more helpful to suggest what value is likely to work.

dm-pde runs to completion when ode_step is reduced to 1
