[Users] Black hole - neutron star binary simulation

[Bruno Giacomazzo]

I have a master's student of mine that is working on NS-BH. We have a
(private) thorn that can read NS-BH initial data generated with LORENE, but
at the moment we are having problems generating good NS-BH initial data
with LORENE (the main problem is getting a sufficiently small initial
separation) and therefore we are currently working with KADATH (
https://kadath.obspm.fr/fuka/). Once we have the data ready, we plan to use
their publicly available thorn to read those data within the Einstein
Toolkit (https://bitbucket.org/fukaws/).

Cheers,
Bruno
