this model still needs to be added. and the README/docs needs to improve to describe each model and how to use it. for the docs, we can use the reproschema doc building mechanism and push to github.

@Hoda1394 - can you take this on?

@satra: just a double-check, should I add the old model here or we want the new model to be added when it is ready?
(I was thinking we want the new model here)

[satra]

the old model instructions. they should be updated when the new model is added.
