Comment:
Hi Travis,
This patch does not pass all of it's doctests. Also, is it a good idea to
add a note to the documentation saying that only Cartan matrices whose
Cartan types are implemented in Sage are legal input? For example, the
Cartan matrix
{{{
CartanMatrix([[2,-3],[-3,2]])
}}}
yields an error. Can you also provide an example of inputting a Cartan
matrix and an index set in the documentation?
