  Compass
  =======
  
  The :class:`Compass` provides access to public methods to use compass of your
  device.
  
  Simple Examples
  ---------------
  
  To enable compass::
  
      >>> from plyer import compass
      >>> compass.enable()
  
  To disable compass::
  
      >>> compass.disable()
  
  To get the orientation::
  
      >>> compass.orientation
      (-23.721826553344727, -5.7114701271057129, -36.749668121337891)

      .. versionadded:: 1.2.0
      '''
  
      @property
      def orientation(self):

          Property that returns values of the current compass
          (magnetic field) sensors, as a (x, y, z) tuple.
          Returns (None, None, None) if no data is currently available.

          return self.get_orientation()

          '''
          self._enable()
  
      def disable(self):
          '''
          Disable the compass sensor.

      (a,b,c,x,y,z)
      # a,b,c denote the Geomagnetic field strength
      # (without hard iron calibration) along the three axes.
      # x,y,z denote the Iron bias estimation along the three axes.
