The ModRosenbroc object provides a numerical ODE solver for stiff systems. Given an unknown, time-dependent function y(t) governed by an Ordinary Differential Equation (ODE) of the form d/dt y(t) = f(t, y) compute y(t) using a (2,3)-order Modified Rosenbrock ODE Integrator (Modified Rosenbrock) or ode.23s Note: the integrateV method for a system of separable ODEs is mixed in from the Integrator trait.

Apply the integrate method to each derivative to compute the trajectory of a time-dependent vector function y(t) governed by a separable system of Ordinary Differential Equations (ODE's) where [f_j(t, y_j)] is an array of derivative functions. Each derivative function takes a scalar t and a scalar y_j = y(j).
