Comment:
I was wondering if we should perhaps have this at the category level, but
I was thinking we might want to consider an infinite tensor product in the
category. So instead I just added a check for finite-dimensionality in the
CFM tensor class.
I also came across this:
{{{
sage: Modules(ZZ).TensorProducts()
Category of objects
}}}
and I decided to fix it here too.
