Boilerplate Heroku Dash App for Long Processes (show and tell)

Thank you so much for putting this together!

I was a bit in over my head when I was going to deploy my first dash app - and then I start getting timeout errors and find I need to use worker processes! which needless to say I knew nothing about…

Having your code as a template for the worker/request/callback structure was super helpful. Thank you thank you!

For other newbies:
In addition to the Wiley template, I referred to: for deploying to Heroku. (be sure to expose the server variable! wasn’t obvious to me that that was important) for managing environments (I’m on Windows, and using conda instead of pipenv)
