Tsitouras 5(4) method

This is an adaptive step size integrator based on a 5th order Runge-Kutta method with 4th order embedded error estimation, using the coefficients from Tsitouras (2011).

Member variables

• tol: The tolerance for the estimated error.
• safety_factor: The safety factor for the step size adjustment.
• min_step_size: The minimum step size.
• max_step_size: The maximum step size.
• max_step_iter: The maximum number of iterations per step.
