Clarify version

[jstclair]

I'm assuming we want to follow semantic versioning because we're down like that?

At least according to the spec, if you've got a version in production, you're already at 1.0.0. So perhaps we should bump the major of master to 1, and (when/if) we promote develop to master, mark that 1.1?

editableCell is most def. in production, so I guess that makes sense.

Gonna bump the version on master to 1.0.0. Then, if/when we merge develop ( #18 ), I think we should bump it to 2.0.0.
