Add Bearing primitive

> In navigation, bearing is the horizontal angle between the direction of an object and another object, or between it and that of true north.
- We use this primitive in the NYC taxi trip problem

```python
def bearing(latlong1, latlong2):
lat1 = np.array([x[0] for x in latlong1])
lon1 = np.array([x[1] for x in latlong1])
lat2 = np.array([x[0] for x in latlong2])
lon2 = np.array([x[1] for x in latlong2])
delta_lon = np.radians(lon2 - lon1)
lon1, lat1, lon2, lat2 = map(np.radians, [lon1, lat1, lon2, lat2])
x = np.cos(lat2) * np.sin(delta_lon)
y = np.cos(lat1) * np.sin(lat2) - np.sin(lat1) * np.cos(lat2) * np.cos(delta_lon)
return np.degrees(np.arctan2(x, y))
