Mini getting-started guide to get the Elevator examples running:

1. Make sure the installation of IndiGolog is correct (read install.txt at the root directory of IndiGolog)
2. Make sure TCL/TK program 'wish' is in the path (in Linux it is often in /usr/bin) (the simulator environment uses a small TCL/TK interface to enter exog. actions async)
3. Go to directory <mypath>/indigolog/Examples/ElevatorSim-BAT and start SWI Prolog with sufficient global & heap memory: /usr/bin/pl -L128m -G128m -T64m
4. Consult main_swi.pl and execute goal "main". Several controllers will be offered. Enter the controller you want to run. That is, in the Prolog prompt that appears do the following: ?- [main]. ?- main. Available Controllers: [1, 2, 3, 4] Which controller do you want to execute? 4.
5. Watch the IndiGolog Agent control the elevator.
6. To run it once again, execute goal "main" again.
