Make it easy to use Isomer with node-canvas

[jdan]

node-canvas is a module that allows you to draw to a virtual canvas and export your drawing as a PNG. I'd like to make it easy to generate isomer drawings with node-canvas.

Doing this means we might need to rearrange some of the files to use a more traditional module pattern - at which point we can probably make it very easy to install isomer from NPM, Bower, and Component.

I'm tempted to say that's a bit heavy. Not sure why you would need an entire library to do this.

document.createElement('canvas') will get you a Canvas element you can work with.
canvasElement.toDataURL() returns a data URL for image/png, though you could specify PNG explicitly if you want by doing toDataURL('image/png').

So people don't have to use a web browser.

My understanding was a bit off. The goal you have I do at work, but just checked some of the source and found that we support canvas on Node.js using node-canvas. So...

Closed via #22. Will update docs on this over the next few days.
