/**
* \fn integrate_adaptive( Stepper stepper , System system , State &start_state , Time start_time , Time end_time , Time dt , Observer observer )
* \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.
