Oleg E. Peil 0c4e3ad006 Changed order of indices of 'proj_arr' array
When a ProjectorShell is created it creates a view of the full
projector array with orbital 'ilm' and band 'ib' indices interchanged.
The reason for this is that this corresponds more naturally to the
definition of the projector P_{m\nu} and also allows for multiplications
of projector matrices without additional transposition.

The tests have been modified accordingly.
