<H2>DESCRIPTION</H2>

v.hull computes the convex hull of a vector points map and outputs the
convex hull polygon in a vector area map. The convex hull or convex envelope
for an object or a set of objects is the minimal convex set containing the given
objects. This module is creating a vector polygon containing all vector
points of the input map.
