Underdash with martyjs?

Opening this ticket to present the thought of merging with [martyjs](http://martyjs.org/).

I'm thinking marty because both marty and alt have evolved into a state where they share a lot more in common than not so this presents a good opportunity to converge.

Why?
- Get more contributors on board.
- Better documentation.
- More examples.
- Increase usage of the library.

Why not?
- Because we might have to make some breaking changes.

This won't be an easy road but we can figure it out.

Thoughts? Concerns?
