Comment:
Volker: I am switching it back to needs review as adding new methods and
actions is not going to happen in the near future and I was not yet going
to change anything existing in this patch. So let me know if there are any
picks that have to be fixed and let's leave the rest to the next ticket
(switching `cone.rays`, `cone.facet_normals`, etc. to this class).
Florent: apart from wrapping tuple special methods, it still seems to me
that goals of this class and elements of Cartesian products are quite
orthogonal, and assumptions on components are completely different, in
particular this class can be switched from tuples to numpy arrays, as
Volker suggested, quite easily, because all components live in the same
space. So I don't think it makes sense to unite these classes, but on the
other hand this ticket shows that tuples can be wrapped efficiently. Maybe
one can do something even better, but I didn't want to mess with memory
allocation and access myself.
