Detailed Description

Implementation of Upwind Nonoscillatory advection schemes UNO2 and UNO3.

See J.-G. Li, “Upstream Nonoscillatory Advection Schemes,” Monthly Weather Review, vol. 136, Art. no. 12, Dec. 2008.

Three more schemes (first-order upwinding, Lax-Wendroff and Fromm) can be stated in the same framework and so we implement them as well since this requires very little effort and simplifies testing and comparisons.
