[SciPy-user] nullclines for nonlinear ODEs

It's really funny, I was planning to add an issue in the Cookbook
about integrating ODE and I chose the Lokta-Volterra model as a basis
too :-)
I still haven't found the time to create the page, and I didn't plot
any nullcline for the moment.

I've just one remark on your example : if you look closely to your
second graph, you can see that the trajectory crosses some arrows of
the direction field. I had this problem too, before forcing matplotlib
to use equal axis.
