      More flags are converted into the new fdfentry method.
      Fixed references for the transiesta electrode setup
      and the mixing variables.
      One should use the fdfindex* variant for sub-options in

      Fixed a few remaining things of the documentation · eee1540f
      Nick R. Papior authored
      Added documentation at the top of the siesta.tex
      file. There a short explanation of the simple
      mechanisms for writing new documentation is created.
      Added nag package which will complain about certain
      use of ancient commands.

      Cleaner fix for init_spin behavior · 9e8f530c
      Alberto Garcia authored
      The nspin, spinor_dim, et al integer pointers in 'm_init' have now
      been initialized to 'null()', and the 'init_spin' routine is now
      called by all processes in 'siesta_init'.  This is the cleanest way to
      fix the problem described in the previous commit.
      Note that the PEXSI routines still use the 'nspin' variable internally
      to refer to both 'spinor_dim' and 'h_spin_dim'. This will be changed when
      mixed-spin solving is implemented.

      Added accuracy control to transiesta on a per-electrode case · 7170066d
      Nick R. Papior authored
      Through fdf-flags one may control the accuracy required for the
      convergence of the self-energies. This enables finer control of
      the self-energy calculations and in some cases it may be useful.

      Fix bug related to init_spin behavior · 11a4dbbe
      Alberto Garcia authored
      The PEXSI-only processes do not call 'init_spin', and rely on a
      broadcast from the Siesta_worker nodes to get certain information. As
      nspin, spinor_dim, et al were integer pointers in 'm_init', they were
      undefined on entry to the PEXSI interface routines, causing segfaults.
      They have been converted to plain integers for now, pending a review
      of other possible ways to fix the problem. 
      Some pointers in sparse_matrices have been initialized to null().
      A test to catch non-collinear or spin-orbit cases has been added
      before the call to the PEXSI solver.
      Note that the PEXSI routines still use the 'nspin' variable internally
      to refer to both 'spinor_dim' and 'h_spin_dim'. This will be changed when
      mixed-spin solving is implemented.
      Added Tests/sih-pexsi-spin.

      Put back the MPI interfaces · 3632a252

      The custom MPI interfaces in Src/MPI are now compiled

      Removed fdf_global module · fec346c6
      Nick R. Papior authored
      - The fdf library inherently handles parallel access.
        Thus the fdf_global module was unnecessary.
        It has been removed and all calls changed.

      Fixes compilation of Nick libraries · 5a50364a
      Nick R. Papior authored
      - libvardict.a has changed name to libfdict.a
        to make it easier to grasp.
      - In both NCDF and fdict libs the PP processor
        command has changed name to CPP (PP is non-standard).
        Further the default CPP command is now $(FC) -E -P -x c
        which may be overwritten using CPP in arch.make

      Clarify the options and filenames to output H and DM · e2206a1a
      Alberto Garcia authored
      For backwards compatibility, a single SystemLabel.DM file
      is produced by default. If the blocked-format option
          Write.Blocked.Matrix T
      is used, a variety of files with the '.blocked' suffix might be
      produced. See the manual for a full explanation.
      Note that the above performance-enhancing option is NOT enabled
      by default.

      Nick R. Papior authored
      - The Charge/Hartree gate is now documented.
      - Added an \ifdeprecated which may be used to
        keep old flags in the manual.
      - The old mixing options are now deprecated and
        partially removed (may be re-instantiated by
        setting \deprecatedtrue in the heading)
        However, the options are not used.

      Enabled size compilation of manual, as well as screen · 51e5af32
      Nick R. Papior authored
      - Updated the makefile for the documentation.
        Now it can build the manual in different formats:
          make SIZE=10|11|12
        will control the font-size of the manual.
      - One can also compile the manual in a screen, two-column format
        which may be easier to read on a big screen.
          make all
        will create all different documentations:
           siesta.pdf, siesta-screen.pdf
           tbtrans.pdf, tbtrans-screen.pdf

      - The tbtrans documentation is nearly complete.
        Currently I think I only need to document the projection
      - The tbtrans manual is a separate document. This is because
        I hope it will encourage the use of tbtrans as a separate
      - Added preliminary placeholder for transiesta article.
      - Updated keywords for electrodes to be more generic.
        Now TSHS == HS and Rep.A1 is not used anymore.
        TSDE == DE
      - Cleaned the molecular mechanics module.

      Removed all references to "contiguous" attribute · 41f4c265

      - Further the atom_graph and m_supercell now have
        restricted their module use to be privatized.
      - All source files have their contiguous attribute
        We should add this as a preprocessor flag in case
        the compiler supports it.
        Several older compilers does not support this :(
