.IX Header "DESCRIPTION"
The \*(L"convex polygon\*(R" around a set of points, is the polygon with a minimal
size which contains all points.
.PP
This package contains one convex calculation algorithm, but may be extended
with alternative implementations in the future.

.IX Item "chainHull_2D(@points)"
Each \s-1POINT\s0 is an \s-1ARRAY\s0 of two elements: the X and Y coordinate of a point.
Returned is the enclosing convex Math::Polygon object.
