Use a different simulation model for live vs. run browsing #60
Description
Currently the app uses a single "simulation" model when accessing the app. This could lead to update collisions if one browser was running in "live mode", and the same user accesses the app from a different window/browser/computer for viewing individual sim runs.
Instead, the app should have 2 default sims, one which gets used for the search page and sim run browsing, and a different sim when "live mode" is selected.
