I have done more reading and research this week and put more thought into the navigation of the program.
I have decided that the decision about navigation should be almost completely random for the scouts, and then 
the foragers should be making decisions based on the pheromone values on which direction they will go.

I have also began to study the Java code that comes with the cmuCam (cmuCam gui program) so that I will 
be able to write my own code for accessing the info from the camera and manipulating that data for my project.
