+  Bearing (position angle) of one point on a sphere relative to another
+  (single precision)
+
+  Given:
+     A1,B1    r    spherical coordinates of one point
+     A2,B2    r    spherical coordinates of the other point
+
+  (The spherical coordinates are RA,Dec, Long,Lat etc, in radians.)
+
+  The result is the bearing (position angle), in radians, of point
+  A2,B2 as seen from point A1,B1.  It is in the range +/- pi.  If
+  A2,B2 is due east of A1,B1 the bearing is +pi/2.  Zero is returned
+  if the two points are coincident.
