Research direction

Start by reading services-turf/src/main/java/com/mapbox/turf/TurfMeasurement.java, especially the bearing function referenced in the issue. Add the requested bearing-difference function and unit tests covering the -179.0 and 179.0 case, including the possible -180.0 and 180.0 results; done means the tests prove the shortest difference.

Written by the indexing model from the issue text.

Description

jira-sync-complete

TurfMeasurement.bearing(Point point1, Point point2

This function can return -180.0, 180.0.

In order to calculate the difference between two bearings. Downstream needs to create a normalizing function which can determine that the difference between -179.0 and 179.0, is 2 degrees.

double TurfMeasurements.shortestBearingDiff(double bearing1, double bearing2) {
  ...
}

This function should be proven with unit tests.
