Enhancements to help with the Economy-style covers. Note that if one wishes to use SpatialRanges (srange) for 'contains', one should 'compress' or 'defrag' the srange first.
0.5.0alpha
Nonconvex calculation is now the default for constructing STARE regions from polygons. Counter clockwise polygons yield the interior+polygon, while clockwise polygons yield the exterior. Uses STARE version at least 0.15.5.
0.4.1alpha
Corrected the sense of the polygon in an example to support the non-convex hull.
0.4.0alpha
A non-convex hull routine has been added.
0.3.0alpha
SpatialRange contains STARE HTM intervals in skip-lists for efficient comparison. This release provides srange, an initial set of functions exposing SpatialRange to Python.
