example tiled code

[dylanmcreynolds]

Provides a sample notebook that shows how to communicate with the tiled server hosted for this project.

Also, splits requirements.txt files so that files used in development are in requirements-dev.txt

I think the gh action failure is because I don't have the ssh key in my forked repo.

I added commits resolving the previous comments.

@danton267 @tamidodo Could one of you take a look at the conflicts in requirements.txt?
Dylan split the file into two such that requirements-dev contains the packages needed only for development.
I would guess that
`gunicorn==20.1.0
requests==2.26.0'
would also better fit into requirements-dev.txt as you added these for deployment in f3989bc and 86d2759
Are there any others that are just for development?

@Wiebke both gunicorn and requests should stay in the requirements.txt file. They're required for the deployment on Dash Enterprise and to download sample files from the GDrive, respectively. Looks good to move black and flake8 to requirements-dev.txt!

(We'll definitely remove any dependencies or files necessary for the Dash Enterprise deployment once we have the deployment set up on your infrastructure).
