    initial v1  
    11Now consider `Polyhedron_base`.

    3 To be honest, I often forget what `join_of_..` and `meet_of_...` mean in this class. I propose to rename them. How do `def face_as_union_of_Vrep(self, *Vrepresentatives)` and `def face_as_intersection_of_Hrep(self, *Hrepresentatives)` sound? I would prefer that the two functions are sort of symmetric. Lines and equations are allowed, but are simply ignored when passing to `self.face_generator()`.

    55In the Hrepresentation, `ppl` backend puts equations first, and `field`, `cdd`, `normaliz` put inequalities first. (I was not able to install `polymake` backend.) Thus, the offset treatment seems needed.
