**Description**


There are two types of Lipschitz estimation used in sizing the disks used in
POF Darts:  ``global`` and ``local``.  The global approach uses
one Lipschitz estimate for the entire domain.  The local approach calculates
the Lipschitz estimate separately for each Voronoi region based on nearby points.
The local method is more expensive but more accurate.
