Publish an npm package supporting extends and abstract?

[labra]

The shumlex project, which converts ShEx to UML diagrams, is based on the ShEx.js parser.

It would be great to add extends and abstract support because they could have nice UML visualization but I think the ShEx.js version published in npm is based on the master branch and doesn't have support for extends yet.

Would it be possible to have an npm package published with support for extends...or are you waiting until they are accepted by the ShEx community group as a new release?

By now, we have opened this issue in Shumlex.
