This script models the behavior of the agent in AI Class
Homework 5, Problem 3: http://youtu.be/212NkM6UCBc

The script prints the model grid and the total number of times a square was
visited by the agent over some number of simulations.

No actual TD-learning takes place in this script, the agent simply tries to
move from the start to the goal by moving to road squares on its preset path.
