double getCurrentStepStart()
This method can be called during integration (typically by
 the object implementing the differential equations problem) if the value of the current step that
 is attempted is needed.
The result is undefined if the method is called outside of
 calls to integrate.
double getCurrentSignedStepsize()
This method can be called during integration (typically by
 the object implementing the differential equations problem) if the signed value of the current stepsize
 that is tried is needed.
The result is undefined if the method is called outside of
 calls to integrate.
void setMaxEvaluations(int maxEvaluations)
The purpose of this method is to avoid infinite loops which can occur for example when stringent error constraints are set or when lots of discrete events are triggered, thus leading to many rejected steps.
maxEvaluations - maximal number of function evaluations (negative
 values are silently converted to maximal integer value, thus representing
 almost unlimited evaluations)int getMaxEvaluations()
int getEvaluations()
 The number of evaluations corresponds to the last call to the
 integrate method. It is 0 if the method has not been called yet.
