Embedded Mermaid diagrams in the IPython Notebook

Embedded Mermaid diagrams in the IPython Notebook.ipynb

This didn't work for me and I found errors in the chrome dev tools that allowed me to find that there was an error resolved in a new mermaid so I'd sub out the above <script> with a link to a current mermaid version from a cdn you can get from say here:
https://cdnjs.com/libraries/mermaid
Also I'm using jupyter lab which didn't have jquery loaded, you can see this if the dev tools give you an error about '$'
to fix that I just added a script tag importing jquery from a cdn.
