A structured recipe notebook for Open Sauces

Here's a prototype recipe notebook for open sauces. At this point it's primarily a test of a drag/drop interface to make it possible for anyone to make the recipe graphs we explored visualising in October. I'm testing it with the recipes designed for FoAM's recent Smoke and Vapour event.

Currently it's structured a bit like Scheme Bricks where you 'read it' inside -> outside, and right to left. We need to look at ways to reverse this - it might be simply making everything float to the right, or more like a bottom up tree, where the finished dish is at the bottom rather than the top.
