npm run pack

Running this npm script will dedupe the module tree, then pack
everything into a tarball. This can then be installed using:

    npm install ./workshop.tar.gz

Can additionally be served over the local network at NodeConf
to avoid requiring the local npm clone, which may be unreliable.
