makePlottablePolytope

 inflate a degenerated and bound an unbounded polytope

 Syntax: [vrep, hrep] = makePlottablePolytope(poly, zerotol, ...
                          flatness, infinityBoxSize)

 A V-representation can be flat, but never unbound. A H-representation can
   be unbounded and flat. Both special cases are covered by the functions
   convertHrepToVrep and convertVrepToHrep.

 See also: viewPolytope, convertPolytope, convertVrepToHrep,
   convertHrepToVrep

• convertHrepToVrep convert the H-representation of a polytope into V-representation
• convertVrepToHrep convert a V-representation into a H-representation
• identifyPolytope returns basic information on the geometric object

• viewPolytope plots a polytope in H-representation or V-representation
