test/requirejs.usecase.html error: Cannot read property 'Digraph' of undefined

[hdon]

Following the instructions in CONTRIBUTING.md, I cloned master, ran npm install, and began loading HTML files in "Chromium 58.0.3029.81 (Developer Build) Built on Ubuntu , running on Ubuntu 16.04 (64-bit)." The exact revision of nomnoml I tested is 9955b94.

When loading one of the HTML files described in CONTRIBUTING.md called test/requirejs.usecase.html I got the following error:

Uncaught TypeError: Cannot read property 'Digraph' of undefined

How does the adoption of require.js look out in the wild? I would like to drop support so that the testing burden is decreased.

I am dropping support for RequireJS. Goodbye!
