/**
 * \class runge_kutta_cash_karp54
 * \brief The Runge-Kutta Cash-Karp method.
 *
 * The Runge-Kutta Cash-Karp method is one of the standard methods for
 * solving ordinary differential equations, see
 * <a href="http://en.wikipedia.org/wiki/Cash%E2%80%93Karp_methods">en.wikipedia.org/wiki/Cash-Karp_methods</a>.
 * The method is explicit and fulfills the Error Stepper concept. Step size control
 * is provided but continuous output is not available for this method.
 * 
 * This class derives from explicit_error_stepper_base and inherits its interface via CRTP (current recurring template pattern).
 * Furthermore, it derivs from explicit_error_generic_rk which is a generic Runge-Kutta algorithm with error estimation.
 * For more details see explicit_error_stepper_base and explicit_error_generic_rk.
 *
 * \tparam State The state type.
 * \tparam Value The value type.
 * \tparam Deriv The type representing the time derivative of the state.
 * \tparam Time The time representing the independent variable - the time.
 * \tparam Algebra The algebra type.
 * \tparam Operations The operations type.
 * \tparam Resizer The resizer policy type.
