Changes (by novoselt):
* keywords: => toric
Comment:
OK, positive review to Volker's patches modulo reviewer's one, which needs
review now.
Changes:
* move `virtual_rays` method to fans only and allow specifying them
during fan construction;
* allow addition of point collections, which results in some
simplification of code and examples;
* a bunch of clarification/typo fixes in the documentation.
Also, am I right that with automatically chosen virtual rays the choice
cannot affect the isomorphism of cones?
