Export a single "Alda" object?

[daveyarwood]

It might be nice if we export a single object that contains all the exported functions, so that this:

alda_cljs.parser.parse("guitar: c e g")

would become:

Alda.parse("guitar: c e g")

(I'm open to other suggestions here.)

We could do this by patching the window object.

We might extend reach a bit (service workers, ES6 projects) by using some kind of UMD-like wrapper instead of just assuming window is available, OK to mutate, and only one version of alda should be loadable.

Or just give out an ES6 module, and let people shim-however-they-want into their project
