|  |  D.13.2.43 minimalFace Procedure from librarypolymake.lib(see  polymake_lib).
 
Example:Usage:
minimalFace(p,v); p polytope, v intvec
Assume:
v lies in the dual tail cone of p
Return:
intmat, vertices of the face of p on which the linear form v is minimal
Note:
the minimal face is independent of the first coordinate of v
since p is considered as a polytope in the plane (first coordinate) = 1.
