Should the exact diagonalization code formula (http://www.itensor.org/docs.cgi?vers=cppv3&page=formulas/simple_ed) show the use of davidson instead of a power method for finding the ground state? It should be more efficient.
Maybe it could be mentioned as an alternative, since the power method is better for teaching purposes.
