This feature may be useful for models that take longer to run (i.e. nested monte carlo). Specifically, this feature may come handy in the following scenarios:
1. When models are run on laptops that need to be shut down for various reasons (i.e. travel and field work)
2. When there is an expected or un-expected power shutdown in the building.
3. Management of priorities. The user can save the paused simulation and focus on other critical tasks that may require CPU power or rebooting before coming back to the paused simulation.
