/**
* \fn size_t integrate_times( Stepper stepper , System system , State &start_state , TimeIterator times_start , TimeIterator times_end , Time dt , Observer observer )
* \brief Integrates the ODE with observer calls at given time points.
*
* Integrates the ODE given by system using the given stepper. This function
* does observer calls at the subsequent time points given by the range
* times_start, times_end. If the stepper has not step size control, the
* step size might be reduced occasionally to ensure observer calls exactly
* at the time points from the given sequence. If the stepper is a
* ControlledStepper, the step size is adjusted to meet the error bounds,
* but also might be reduced occasionally to ensure correct observer calls.
* If a DenseOutputStepper is provided, the dense output functionality is
* used to call the observer at the given times. The end time of the
* integration is always *(end_time-1).
* If a max_step_checker is provided as StepOverflowChecker, a
* no_progress_error is thrown if too many steps (default: 500) are
* performed without progress, i.e. in between observer calls. If no
* checker is provided, no such overflow check is performed.
*
* \param stepper The stepper to be used for numerical integration.
* \param system Function/Functor defining the rhs of the ODE.
* \param start_state The initial condition x0.
* \param times_start Iterator to the start time
* \param times_end Iterator to the end time
* \param dt The time step between observer calls, _not_ necessarily the
* time step of the integration.
* \param observer Function/Functor called at equidistant time intervals.
* \param checker [optional] Functor to check for step count overflows, if no
* checker is provided, no exception is thrown.
* \return The number of steps performed.
