#NOTE: $meWeight and $themWeight should really add up to a constant value.  
#      Swarm Intelligence defines a 'pso random range' constant and then computes two random numbers
#      within this range by first getting a random number and then subtracting it from the range.
#      e.g. 
#           $randomRange = 4.0
#           $meWeight   = random(0, $randomRange);
#           $themWeight = $randomRange - $meWeight.
