Comment (by novoselt):
Hey Volker - I think it would be nice to deprecate in this ticket
everything that we don't want to keep except for the way how faces are
handled (which I'd rather do in a follow up ticket). So far I've
deprecated constructing polytopes from matrices, perhaps constructing them
from files should be deprecated as well and handled by separate functions?
What about "desc"? I'd like to print polytopes similar to cones/fans: "3-d
lattice polytope in 4-d lattice N", perhaps with "lattice" replaced by
"reflexive" automatically and with the index for 2- and 3-d cases. Should
then "desc" be gone and those who really want can use Sage standard
"rename"?
Also, I am not sure what the output of "normal_form" should be - keeping
it as a matrix does not seem a good choice. Maybe the corresponding
polytope in `ToricLattice(dim).dual()`? Then polytopes from built-in lists
will return themselves and be equal to their normal form.
`projective_space` and `octahedron(2)` better disappear as well, not sure
how did I come up with "octa" for vertices other than 8!
