Meetup outreach re-run with different topic

[parente]

Run it once top to bottom. Then go back and change the topic of interest variable. Then run it again.

Looks like that notebook has a cell that is defining a polymer element. You will always run into that problem unless you protect that cell from multiple executions.

One idea is to store the return of the Polymer() call to a global and test around it.

When we can bundle external files with deployed dashboards (#11) we can define the Polymer element in a separate file. This will also be beneficial for reducing code in the demo notebook.

For now, do the quick fix: make it global and check if already defined.

Added PR #65 to fix this.

Will open an enhancement for later about migrating the widget out of the notebook to test @nitind's association work.
