Lack of library version

[kossnocorp]

Hi,

at first thanks for great library!

But why you don't use versioning? It's complicate update your library. I suggest to use Semantic Versioning (http://semver.org) it's easy to understand and semantic.

Cheers!

The package.json includes a version string, which by happy coincidence is semantic. :)

Integrating it with git tags would be worthwhile though.
