RobotWalk.js

• This script is in charge of moving the camera according to a pre-programmed series of waypoints we read in from a text file.
• Each line of the file should be in the format "X,Z,P", where (X,Z) is the waypoint and P is a binary value indicating whether an object will be viewed by reaching that waypoint.
• Note that the route waypoints must trace a grid - only 90 degree turns are currently supported.
