Comment (by novoselt):
Glanced through, spotted a few typos that I'll fix in the reviewer patch.
What do you mean by the following change of output description??
{{{
By default, ``True`` if ``self`` and ``other`` are in the same
`GL(n, \ZZ)`-orbit, ``False`` otherwise.
}}}
Do you mind if I also switch computation of the virtual rays to the fan
constructor and allow user to specify them? It is convenient e.g. when
considering an affine toric variety corresponding to a face of another
cone, or a subfanfan with similar structure. Then coordinates on the
smaller variety can match the bigger ones.
