Rename on(), off() functions to watch(), ignore()

[danhardman]

I've only renamed the fields on the returned singleton for now to keep things simple, but I think on() and off() functions don't make sense without an attributed action. Typically you'd get on('click',...) for example.

This just makes things clear that you're setting up a watcher/listener on the CSS selector.

Thanks! Let me think about it some more. I used on/off for symmetry with jQuery but I like watch(). What do you think of disconnect() instead of ignore()?

[danhardman]

Yeah it kinda clicked that ignore() probably isn't the best name if its intended to only work when a watcher is already setup on that selector. disconnect() or stop() I think would work well.

How about observe() and disconnect()? MutationObserver has these methods.

What about subscribe() and unsubscribe() like with es6 observables [1]
