It should be straightforward to change it. Actually, we do write the
eigenvecs in every geomtry iteration, they just get overriden in the
next one. In dftb+.F90 around line 1835 the writing of the eigenvectors
starts. The correpsonding routines are in mainio.F90. Just pass as an
additional paramater the current step number and add that as suffix to
the file name. Then, you would have all eigenvectors.
