Spherical coordinates

Alternative, we can compute the gravitational fields of point sources defined
Alternatively, we can compute the gravitational fields of point sources defined
in a spherical coordinate system. To do so, we need to pass the
``coordinate_system`` argument as ``"spherical"```. The coordinates of the
point source must now be passed as *longitude*, *latitude* and *radius*, where
the two former ones must be in decimal degrees and the latter in meters.

Lets define a single point source in the equator, at a longitude of 45 degrees
and located on the surface of the WGS84 ellipsoid.
