Comment:
There are multiple references to "the criteria of
:class:`ToricEmbedding<ToricEmbedding_Mixin>`" yet upon looking into
docstrings of that class these criteria are not clear. There are also
tests where it seems that the same morphisms are constructed, yet they
compare unequal. Would be nice to have a precise definition of what is
considered an embedding morphism and why it is necessary to compare equal
morphisms as unequal.
