Detailed Description

Two stage, singly diagonal implicit Runge-Kutta (SDIRK) methods; the choices for gamma_opt are: 0 - 3rd order method, not A-stable 1 - 3rd order method, A-stable, not L-stable (default) 2 - 2nd order method, L-stable 3 - 2nd order method, L-stable (has solves outside [t,t+dt]).
