Another change will be available in the next build, Population Models. The
purpose of a population model is to handle general effects on a population
that is not caused by a disease outbreak. Right now, there is only one
Population Model available that allows you to define a background birth
and death rate for your scenario. Some things to note:

1. Background birth rate and death rate are not available any longer in
the standard disease models. They have been moved to a Population Model.
So for old scenarios where you had your birth/death rate defined you need
to create a new population model, specify your birth/death rate and drag
it into your scenario.

2. To create a population model, go to the menu (New -> Population Model).

3. A population model is just like a disease model (it ends up under
decorators in the project explorer) and it will store its own log files
under its name in the log folder

4. Disease models and population models should work well together and
synchronize up background birth/deaths and disease deaths among each other
each iteration. If you don't have a population model in your scenario, the
background birth/death rate is 0. When 2 or more diseases are running
simultaneously they will incorporate each others disease deaths into their

Let me know if there's any problems.
