New description:
As the summary says, this patch improves eigenvalues of matrices with
double-precision floating-point entries.
1. Uses !SciPy's `eigh` routine for symmetric and Hermitian matrices.
1. Allows grouping of "equal" eigenvalues, based on a tolerance
parameter.

Comment:
I thought this was OK and I just triple-checked, and I think it is OK.
One change: made "warning" all capital letters, this is the only change to
the v2 version of the update patch.
The HTML documentation renders the warning blocks as they should. I'm
going to move this back to positive review.
Jeroen - please let me know if I am really missing something here.
Thanks.
Rob
