function n = dim(POLY)

% Dimension of the space containing a polyhedron object 
%
% Syntax:
%   "n = dim(poly)"
%
% Description:
%   "dim(poly)" returns the dimension of the space in which "poly" resides. 
%
% Examples:
%   Given a polyhedron object, "poly" representing a square in the x3 = 0
%   plane with corners at (x1,x2) pairs (2,1), (2,3), (4,3), and (4,1)
