Simple ODE stepper from boost.

This is a simple implementation of the Boost “Error Steppers” into the O2scl framework. The slightly different interface requires a function wrapper (ode_funct_boost) and an extra copy of the state vector. This works with the steppers runge_kutta_cash_karp54, runge_kutta_dopri5, and runge_kutta_fehlberg78. The Boost stepper runge_kutta_cash_karp54 gives identical results to ode_rkck_gsl.
