Module Cvodes

Sensitivity analysis (forward and adjoint) and quadrature equations for CVODE.

These submodules extend basic state functions, $\dot{y} = f(t, y)$, with parameters $p$ and quadrature variables $y_Q$. The former exposes a new dependency, $\dot{y} = f(t, y, p)$, relative to which the sensitivity of a solution can be approximated. The latter effectively suppresses a dependency ($y_Q$ is disjoint from $y$), $\dot{y}_Q = f_Q(t, y, p)$, to reduce computation costs.
