=head1 NAME
Math::Polygon::Convex - Collection of convex algorithms
=head1 INHERITANCE
Math::Polygon::Convex
is a Exporter
=head1 SYNOPSIS
use Math::Polygon::Convex qw/chainHull_2D/;
my @points = ( [1,2], [2,4], [5,7], [1,2] );
my $poly = chainHull_2D @points;
=head1 DESCRIPTION
The "convex polygon" around a set of points, is the polygon with a minimal
size which contains all points.
This package contains one convex calculation algorithm, but may be extended
with alternative implementations in the future.
=head1 FUNCTIONS
=over 4
=item B<chainHull_2D>($points)
Each POINT is an ARRAY of two elements: the X and Y coordinate of a point.
Returned is the enclosing convex L<Math::Polygon|Math::Polygon> object.
