Description
Currently the UpwindOperator type implements a pure upwind scheme (in terms of it its stencils). Additionally, biased upwind schemes which utilize a specific number of off-sided points would be a useful functionality. For instance, the following paper describes a biased upwind scheme utilizing a single off-sided point: https://www.sciencedirect.com/science/article/pii/S0378475401002889
The default number of off-sided points should be zero, defaulting back to the pure upwind scheme that is currently implemented.
