Fix some issues related to the Courant number
...
step_h was using the wrong timestep; fixing it caused update issues
based on the Courant number being 1.0, i.e. too large. Reducing it to
\sqrt{3}/3 fixes stability issues. Unfortunately, a non-Unity Courant
value prevents me from using the ideal Absorbing Boundary Condition I
had just implemented, so that's been disabled.

step_h uses optional left/down nodes.
...
This will be handy for implementing 3d, because the world with depth=1
(i.e. no neighboring xy planes) will behave the same as a 2d simulation.
