Support attribute sourcing

[ockham]

Here's a very bare-bones, WIP, implementation of attribute sourcing.

For more background, refer to @luisherranz' great video in #27.

Feel free to pick it up and play with it; otherwise, I'll continue working on it on Friday 🙂

matcherFromSource is a wrapper around hpq's parsing functions (e.g. text or html) , which expects a DOM element tree. Good thing that this is one! 😄

This is looking great 🙂

I was originally planning to add support for more attribute sources here (html, query, meta, etc -- see), but now I'm thinking it might not add much value to the proof-of-concept (and just amount to copying code over from GB).

So maybe this is ready for review/merging?

Sure, approved so you can merge as you please 🙂

However, would you mind adding a non-sourced attribute before you do so? Just a simple one can do. If not, the demo won't ship any non-sourced attribute anymore.

Thanks, good point! I made the counter value an attribute (i.e. it's now possible to set the initial counter value from the editor). (Changing it on the frontend won't persist it, though.)

Okay, Imma go ahead and merge this 🙂

Awesome. Thank you, Bernie 🙂
