See note in the docstring, and Milstein Method on Wikipedia. For now, we will assume that \sigma'(x) is zero for most applications, making this method equivalent to the current one.

Needed for porous media models. It's worth noting in the documentation somewhere that D for porous media should be the effective diffusion constant divided by volumetric water content. See this paper.
