Teodoro Laino 1653374404 Here we go.. Let's start with free energy methods.. UI implementation..
One more regtest. Reorganization of themetadynamic section. now all free
energy method are contained in a main folder called free_energy.
Cleaning the regtest directory of fist, moving the xyz, pot and psf files
in correspondingly appropriate directories. few more work on free energy
calculations later on..
