bearing

Description

Calculates the Bearing between two points. The bearing is the compass direction to travel from a starting point, and must be within the range 0 to 360.

Signature: ds.feature_engineering.bearing(lat1, long1, lat2, long2)
Docstring:
Calculates the Bearing  between two points.
The bearing is the compass direction to travel from a starting point, and must be within the range 0 to 360. 

Parameter:
-------------------------
    lat1: scalar,float

        Start point latitude of the location.

    lat2: scalar,float 

        End point latitude of the location.

    long1: scalar,float

        Start point longitude of the location.

    long2: scalar,float 

        End point longitude of the location.

Returns: Series
