There are four demos included with this code.

1. Simple Stretch demo. Copy "config.4Stretch.txt" to "config.txt" and run 
"./runStretch". This creates four linked Stretches and a RandomVehicle that 
creates five Vehicles to travel through the Stretches. Once all five Vehicles
have left the simulation, the simulation terminates.

2. Atlanta Interstate demo. Copy "config.Atlanta.txt" to "config.txt" and run
"./runStretch." This creates 36 linked Stretches simulating the Atlanta 
interstate highway system. It also creates a RandomVehicle that creates one 
Vehicle and sends it into the simulation. Once the Vehicle leaves the simulation
(which can only occur when the Vehicle leaves Atlanta on I-85, I-20, or I-75),
the simulation terminates.

3. Simple (prototype) monitoring/steering demo. Copy "config.SimpleMSLP.txt"
to "config.txt" and run "./runSimpleMSLPTest". This creates a SimpleMSLP and an 
Adder LP. In a separate window, run "java SimpleMSApp" to launch the simple M/S 
application. From SimpleMSApp, you can send numbers to the SimpleMSLP, which 
passes them as simulation messages to the Adder, which adds 1 and passes the 
result back to the SimpleMSLP, which passes the result back to SimpleMSApp for 
display.
NOTE: Since this is a prototype demo, the simulation will not end cleanly. It 
must be manually terminated; be sure to check for any leftover processes that 
must also be killed.

4. Stretch monitoring/steering demo. Copy "config.StretchMS.txt" to 
"config.txt" and run "./runStretchMS". This creates an MSLP, a ControllerLP
(to keep the simulation alive while waiting for input), a RandomVehicle, and
four linked Stretches. In a separate window, run "java MSApp" to launch the 
M/S application. From the MSApp, you can send arbitrary callback messages to 
arbitrary LPs. By choosing to send a message to "All LPs" you can broadcast a 
single message to every LP in the simulation. Two good ones to start with are:
Target APPid: All LPs
Command: getAPPid
Value: (doesn't matter)
and
Target APPid: All LPs
Command: listCallbacks
Value: (doesn't matter)
To cleanly end the simulation, send:
Target APPid: O (the ControllerLP)
Command: setLifeSupport
Value: 0 (off)
Once the simulation ends, enter a target APPid of -1 to quit MSApp.
