I started branch vgl/require-js-loader to explore using requirejs to load dependencies within the project. I wrote a shim in src/init.js that will keep the code working until we start building with it. I converted src/actor.js to use the define call. I am looking for some feedback on the style. It will take a significant amount of work and a large diff to make the change, but it won't change the API from the user's perspective.

The overall benefit of this beyond making the CMakeLists file more maintainable is that we can easily examine the dependencies between modules. The class inheritance style that currently exists allows me to create graphs like the one attached below, but with a full view of the dependency tree.
