create wiki to link to atlantis models worldwide

[andybeet]

I wonder if we can create a wiki either in this repo or in another where we compile info from the summit and link to atlantis models being used worldwide. Be happy to be part of this.

Not proposing anything that would duplicate content on the confluence site but more related to applications of the model

I think that is a good idea. It will also allow people to see what other teams are doing with Atlantis. It is also a good way of promoting Atlantis with other communities. Maybe this repo will be the right place. We can also add a map and a table with the application and link to the models.
