images in a cluster calculation. Still to be tested in parallel, it
has been tested for Gamma vs 0 0 0 and for nspin=1 and 2. Forces seem
to be ok. In the few cases considere there is no significant increase
of workload with respect to the periodic calculation.
plot_io.f90 moved from PP to flib because it may be needed
in PW/martyna_tuckeman.f90 for debugging and in this way circular
references are avoided. It only USE low-level modules like io_global,
kinds, and constants so it should be ok.
Module ws_base.f90 added in Modules. It deals with basic operations
associated to Wigner-Seitz cell. The implementation should be general;
it has been tested for SC and FCC only.
