     * \brief Integrates the ODE with adaptive step size.
     * 
     * This function integrates the ODE given by system with the given stepper.
     * The observer is called after each step. If the stepper has no error 
     * control, the step size remains constant and the observer is called at
     * equidistant time points t0+n*dt. If the stepper is a ControlledStepper,
     * the step size is adjusted and the observer is called in non-equidistant
     * intervals.
     *
     * \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 start_time The initial time t0.
     * \param end_time The final integration time tend.
     * \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.
     * \return The number of steps performed.
