Comment (by ncohen):
Also, I am not totally sure that I understand the definition of the
Hashimoto matrix. To me it sounds like `g.line_graph().adjacency_matrix()`
(i.e. the adjacency matrix of the line graph), but I am not totally sure
`O_o`
It sounds a bit weird to me that this matrix seems to depend on whether an
edge `(i,j)` is returned as `i,j` or as `j,i`.
