TspWalk.js

• This script is in charge of moving the camera according to a pre-programmed series of steps, which it reads in from a text file. Unlike RobotWalk, if a straight line between consecutive points does not fall on the grid, TspWalk will add in intermediate points to make the route navigable. Note that the grid layout is specific to level MultiGrid.
• The reading-in code and navigation code is redundant with RobotWalk, but the intermediate waypoint code is distinct. These two scripts could be merged, or this one could use/call RobotWalk, in future versions.
