d969608541 EVOLUTION: Implement step repetition in evolve_ssprk3_m(). 
If the desired tolerance was not achieved, the integration step is
repeated. The tolerance is controlled by two parameters:
"absolute_tolerance" and "relative_tolerance". The number of allowed
repetitions is controlled by parameter "maximum_repetitions".
