   The ETDRange class provides a trajectory-based, nonparametric approach to estimate the utilization distribution (UD)
   of an animal, using model parameters derived directly from the movement behaviour of the species.get_displacement

.. py:function:: grid_size_from_geographic_extent(gdf, scale_factor = 100)

   Intended for use as input to create_meshgrid and RasterProfile.
   Uses pyproj.geod.inv to determine the distance of the diagonal across the bounds of a gdf,
   and divides by the scale_factor to determine a 'sensible' grid size in meters
