Oleg E. Peil 3317371762 Added calculation of density matrices for a shell
A method 'density_matrix()' for evaluating a density matrix of a given shell
has been added to class ProjectorShell. It requires an ElectronicStructure
object as an input an by default produces a site- and spin-diagonal
part of the density matrix using the Fermi-weights obtained directly from VASP.
Ideally, this density matrix should coincide with the one calculated
within VASP itself (inside the LDA+U module).

Corresponding sanity test has been added, which shows only that the
calculation does not crash. Real numerical tests are needed.
