cone(Polyhedron) -- Take the cone over a polyhedron

Description

The polyhedron is embedded at height one, then the cone is taken over it.

i1 : P = hypercube 2

o1 = P

o1 : Polyhedron

i2 : vertices P

o2 = | -1 1  -1 1 |
     | -1 -1 1  1 |

              2       4
o2 : Matrix QQ  <-- QQ

i3 : C = cone P

o3 = C

o3 : Cone

i4 : rays C

o4 = | 1  1  1  1 |
     | -1 1  -1 1 |
     | -1 -1 1  1 |

              3       4
o4 : Matrix ZZ  <-- ZZ
