I decided to merge this tonight since it strictly dominates the current docs. The new docs will be available at https://odow.github.io/SDDP.jl/latest/ once the build finishes.

I'll keep writing and address the remaining TODO's tomorrow.

cc @adow031, this should help your Part IV students.

@Thuener, @lorenzoreus, @bfpc I'm finally getting around to doing this, the new docs may be of interest.
