The device has no magnetometer (issue #16): north is given by the course
over ground while walking, or by aiming at the sun, and the gyroscope
follows the turn around the vertical in between. With the sun's position
from the time and the place, the bearing to a point, the 16 points and
distances as text. Host-tested.
