'''Property that returns values of the current device orientation

|
as a (azimuth, pitch, roll) tuple.
|
|
|
|
Azimuth, angle of rotation about the -z axis. This value represents the
|
|
angle between the device's y axis and the magnetic north pole.
|
|
The range of values is -π to π.
|
|
|
|
Pitch, angle of rotation about the x axis. This value represents the
|
|
angle between a plane parallel to the device's screen and a plane
|
|
parallel to the ground.
|
|
The range of values is -π to π.
|
|
|
|
Roll, angle of rotation about the y axis. This value represents the
|
|
angle between a plane perpendicular to the device's screen and a plane
|
|
perpendicular to the ground.
|
|
The range of values is -π/2 to π/2.
|
|
|
|
Returns (None, None, None) if no data is currently available.
