Example `LocationMixin` class that can be used to provide geolocation to any `SQLModel` class.
max_radius_of_earth = 6500 * 1000 # metres
max_sqrt_distance = math.sqrt(max_radius_of_earth * 0.95)
min_sqrt_distance = math.sqrt(100)
class LocationMixin(object):
"""Provides ``self.latitude`` and ``self.longitude`` attributes and a
``self.update_location()`` method which updates ``self.location``,
which is stored as a geography type in latlng projection.
You can keep self.location uptodate automatically by binding to
