Navigation: 
          1. randomize navigation choices on direction should be random in the case of no pheromone (although
             the scout will still smell for  the pheromone value even though negligable)
          2. navigation should depend on pheromone values otherwise 
          3. the directional array (array that holds the value of how the ant got to the food
             will now be used to navigate back to the nest.)

pheromone values will be based upon three scouts paths: red path, yellow path, blue path
at each decision station, i.e. a choice to turn onto bridge or onto path (marked by tape or sensed by camera)
the forager will look at the pheromone values transmitted by brain and make a choice based on the
strength of the scent.

The first scout to finish comes to food.  Camera is designed to look for three blobs: either red, blue or yellow. 
It defines who finished then sets pheromone value for it.  When blue finishes it does the same and for yellow.  The 
three blob's information (the boe-bots with colored markers) will be held in an array.
The next step will be to work on this program to see if it will work.

Brain: The brain will need to be able to get the info from the three different scouts and give them a pheromone 
value and keep transmitting the three
