    """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 AddPixelEvent).
