Simple Population Model: Runtime Frame

This very simple model demonstrate the basic features of stocks and flows. The equation in the flow is evaluated at each time step and adds its value to the value of the stock, which keeps a running tally of total population. There are both growth and loss dynamics, which rely on the values respectively defined by the sliders birth_rate and death_rate. times the total population at a given time step.
