Print out density functional citations and Libxc version
Currently, VeloxChem uses Libxc without attribution. Whenever Libxc is used, VeloxChem should print out the literature reference of Libxc, available with the xc_reference()
function, as well as the employed version of Libxc, available from xc_version_string()
, which is important for later reproducibility.
In addition, the program should print out the literature references to the employed density functionals, which are all provided by Libxc.
