[stem-dev] new Corona Virus Model

["James Kaufman" <jhkauf@xxxxxxxxxx>]

Greetings STEM community.
With a colleague we created a global model for Corona Virus and made it
available on the downloads page. I also added some documentation here.
We tested the
download but would very much appreciate your help testing in on your platform
and feedback on the documentation.

Please help with
any improvements to the doc. This is not a calibrated model but an platform
for hypothesis testing. We are at CDC in Atlanta and there is interest
here in the ability to quickly test a model with an asymptomatic state.
