VERT2CON - convert a set of points to the set of inequality constraints which most tightly contain the points; i.e., create constraints to bound the convex hull of the given points

[A,b] = vert2con(V)

V = a set of points, each ROW of which is one point
A,b = a set of constraints such that A*x <= b defines the region of space enclosing the convex hull of the given points

For n dimensions:
V = p x n matrix (p vertices, n dimensions)
A = m x n matrix (m constraints, n dimensions)
b = m x 1 vector (m constraints)

NOTES:
NOTES:
(1) In higher dimensions, redundant constraints can appear. This program detects redundancy at 6 digits of precision (per dimension), then returns the unique constraints.
(2) See companion function CON2VERT.
