9 : !> \brief New version of the module for the localization of the molecular orbitals
10 : !> This should be able to use different definition of the spread functional
11 : !> It should also calculate the integrals analytically so that it can be
12 : !> used irrespective of the pw_env and the collocation of wfn on the grids
13 : !> It should also work with a selected set of states, instead than all of them,
14 : !> in this case one should check that the selected states have the same occupation number
15 : !> The spread functional can be only estimated, or also optimized by minimization
16 : !> and in principle also maximization should be available.
17 : !> This operations can be required irrespective of the printing requirements
18 : !> It would be highly desirable to do all this along a MD run every N steps,
19 : !> and have a trajectory of the centeroids of the localized wfn
20 : !> In addition these functions can be used for properties calculations
21 : !> like NMR and XAS. Therefore it is necessary that the rotated wfn are then copied
22 : !> in the mos fm matrix to be available for next use.
