In this release

• a first version of the JSMEEditor is included.
  • We created a draft of a nice reference notebook.
• we released the first panel-chemistry package to Pypi. Check out https://pypi.org/project/panel-chemistry/
• We improved the look and feel of the project

This release add a JSME Editor Widget. But only as a dummy widget.

The idea is to demonstrate that the easiest way to add a new Bokeh/ Panel extension is to start as simple as possible. And that is to copy some existing small component, refactor minimally, build and test it works. Then you can start refactoring and extending the component.

You can see how this was implemented in this video https://youtu.be/AA8qIY_zrbA

Supplementary written documentation can be found in

• Bokeh - Extending Bokeh
• Awesome Panel - Bokeh Extensions

Have run bokeh init --interactive as described in

• Extending Bokeh
• Awesome Panel - Bokeh Extensions

and aligned package.json and tsconfig.json with the same files in the Panel project.
