#Abstract class for a behavior.  On every time step, the behavior is passed the
#inputs from all sensors it is bound to as well as any recursive inputs that it
#spawned during the last time step.  Inheriting classes MUST define
#processResponse.  processResponse should return a list of dictionaries which
#define the properties of the light response, (outputs, recursions).  They must give a location and
#color.  They may define a PixelEvent to more closely control the outgoing
#data, however, this is normally handled by routing the event to a behavior
#specifically designed to do this (like DecayBehavior).
