 * \brief Two-phase problem featuring some gravity-driven saturation
 *        fingers.
 *
 * The domain of this problem is sized 10cm times 1m and is initially
 * dry. Water is then injected at three locations on the top of the
 * domain which leads to gravity fingering. The boundary conditions
 * used are no-flow for the left and right and top of the domain and
 * free-flow at the bottom. This problem uses the Parker-Lenhard
 * hystersis model which might lead to non-monotonic saturation in the
 * fingers if the right material parameters is chosen and the spatial
 * discretization is fine enough.
