How to use the Bangle.js Layout library

Since there appears to be some interest in lazy rendering, I've created pull request implementing it in the Layout library.

Just pass the third argument {lazy: true} to the layout constructor, and updates are as easy as:

layout.time.label = require("locale").time(d,1);
layout.update(); // Only needed if there's a chance that something moved
layout.render();

Edit: I see my demo has the same issue as before. If it gives you any errors enable "Pretokenise code before upload" in the web ide settings.
