This is not really a license per se, but a copy of the e-mail from
Ziheng Yang giving us permission to include his source code in the distribution. Questions regarding the license specifics for
this module should be addressed to Ziheng at the e-mail address
below.

Hi Gavin,
You have my permission to use the codes for matrix exponential and eigen
calculation. I won't take any responsibility for any errors in the source
code.
Are you using the code for a symmetrical real matrix (or for a
reversible-process rate matrix) as well?
Best,
Ziheng
