/** 

This is the main program users of the simulator write to create and initialize entities 
and decision makers in the environment and to start up the control loop of the simulator.  
This program in particular is used to automatically generate specified numbers of 
interconnected locations, evacuees, safety locations to which evacuees are evacuated,
and transports for carrying the evacuees.  While these numbers are hardcoded in this 
program, the SimulatorStartFrame class lets a user specify the values at runtime in 
another window.
