bearing property
Bearing is the direction that the camera is pointing in and measured in degrees clockwise from north.
The camera's default bearing is 0 degrees (i.e. "true north") causing the map compass to hide until the camera bearing becomes a non-zero value. The mapbox_uiCompass boolean XML attribute allows adjustment of the compass' visibility. Bearing levels use six decimal point precision, which enables you to restrict/set/lock a map's bearing with extreme precision. Besides programmatically adjusting the camera bearing, the user can place two fingertips on the map and rotate their fingers.
