issues:

1. npm version of jupyterlab doesnt match github master branch
2. unclear how to pass options.paths.urls.baseUrl to JupyterLab constructor and unclear if the constructor even uses it
3. unclear how to modularize jupyterlab front end from jupyterlab server.
4. unclear how to sync react state with jupyterlab
5. unclear exactly why the current bug arises
6. impossible to search jupyterlab api docs across all packages and the version number is not shown
