Put the first Holoviz implementation on AE5 as a web app and demo it

Demo it to USGS and put it up on AE5 as a web app that they can start to play with and give feedback on.

Doodler is now is a good state (even if I've noted some instabilities I have to look into) and can be deployed, at least for testing purposes. @jlstevens I think I'll need your help to deploy it on AE5 since I've never done it 🙃 Let's see if we find time to address that first week of January.

I'm not familiar with what AE5 is, but a web app demo would be useful for easier discussion and to iron-out any potential deployment kinks

Would you deploy using Docker?

[jbednar]

AE5 is what the examples at examples.pyviz.org all run on; it does use docker (via kubernetes) but it hides all that behind a simple yaml configuration file that specifies a conda environment and a command to run in it. The same file (an anaconda-project.yml) can generate a docker image if that helps you deploy it on other systems.
