DESCRIPTION

       This  engine  has  three  triggers as input and two Boolean values as output. The isOn output is a switch
       that can be turned on or off by  triggering  the  corresponding  input.  You  can  toggle  the  value  by
       triggering the toggle input. By default isOn is FALSE. The isOff output value is the inverse of isOn

INPUTS

     SoSFTrigger         on
          Turn the isOn switch on.

     SoSFTrigger         off
          Turn the isOn switch off.

     SoSFTrigger         toggle
          Toggle the switch value.

OUTPUTS

     (SoSFBool)          isOn
          Switch value.

     (SoSFBool)          isOff
          The inverse of isOn.

METHODS
