Summary
The minimum step check was sometimes bypassed when updating the step size for the next integration cycle. This could cause the minimum integration step size to be zero, thereby hanging forever. This PR also prevents NaN from showing up in the solution of an integration by stopping the integration and recommending solutions.
This PR fixes #377 where this bug was identified. Thanks @gregjesl !
