update:
found a bug in the stopping condition for iloop > nloop. fixed in all drivers.

update.
- evaluates spin-spin and density-density correlations <n_a,n_b>
- introduced numbering in the columns.info file from greater readibility.
bugs fixed:
- now evaluates spin-spin <sz_a,sz_b> rather than moment-moment <m_a,m_b> correlation
function.
- found a bug in the printing routine for the irreducible bath chi^2 fit:
always printed G0 field rather than G0 or \Delta depending on the value of
cg_scheme.
- new bath initialization: generate a smart bath in the range -Hband:Hband (input of
ed_init_solver, default=2) and optionally read bath from file so that
restarting from different bath levels is possible. bath center is at 1.d-4.

reshape:
code structure slightly updated.
Input variables are pushed into a separate module to better handle wrapping into larger codes (e.g. RDMFT).
The global variables are still kept into the ED_VARS_GLOBAL module. A separate module was created for the BATH_TYPE which
can NOT be included in the ED_BATH module, because this latter needs some global variable on its own.
