## Methods:

new ([djointgroup])
  returns: (djointslider)
  When the axis is set, the current position of the attached bodies is examined and that position will be the zero position.
axis ([float x,y,z])
  returns: ([float x,y,z])
  sets/gets axis of slider. Must be attached first, else crash is likely
position (djointslider)
  returns: ([float position,positionrate])
  Get the slider linear position (i.e. the slider's 'extension') and the time derivative of this value.
