- simplified ionic positions management in FPMD ( many staff moved to
Modules/ions_base.f90
- sort_gvec.f90 ( a part of ggen common to FPMD and CP )

The +U part of the functional can be built using
for the projection on localized orbitals some simple
Wannier functions generated by the post-processing
code poormanwannier.f90 (pmw.x) from the LDA band
structure. (SdG)

This required a deep modification of the parallelism in PWscf:
there are two new communicators (intra_image_comm and inter_image_comm) and the
existing "pool" communicators (intra_pool_comm and inter_pool_comm) are now vectors
of length given by the number of parallel images. #ifdef __PARA is no longer
needed because all "parallel" variables are always initialized for a serial run
and all parallel routines are, in the case of a serial run, dummy routines.
The wrappers to MPI routines used only by PWscf are in the PW/para.f90 file.
The others (mp_***) are in the Modules/mp.f90. All explicit referencies to mpif.h
should be replaced by an "USE parallel_include" (in a serial run parallel_include
is simply a dummy module).
2) The extrapolation of both potential and wavefunctions has been rewritten in
order to be smarter than before: on the basis of the required extrapolation
order, on the basis of the history and on the basis of which files are really
present on the disk, the algorithm chooses the extrapolation order.
All the algorithms in which ions are moved can use the extrapolation.
These are both unstable features: I need the help of everybody to test them.

The same bug is present in the 2.0.1 version and in the patch-2-0p2.
This should be the ultimate fix for defaults-related problems.

when a calculation was restarted wfc were always read by file
(no matter whether the startingwfc keyword was set or not).
The same was true for the potential.

Molecular Dynamics based algorithm partially rewritten:
both standard and damped MD are performed with the velocity Verlet
scheme (with or without constrains).
Renata's subroutines are used only in the framework of variable
cell.
constrain.f90 file is no longer needed: cnstrains are set in the
input file (see CONSTRAINTS CARD) with the same input format used
in FPMD. An arbitrary number of constrains can be set.
In the case of constrained relaxation the damped MD
algorithm is used instead of BFGS.
When restart_mode = "from_scratch" many reastr files are removed
from the scratch directory.
Several other modifications here and there. (C.S.)

matrices. Useful when the default choice take the wrong
(or not desired) path.

correct place (kinds); module "varie" replaced by "control_flags" (not
yet in pwcom, though) - many many files changed.
64-bit cpus (Opteron, maybe Itanium) should now work if __LINUX64 is defined

This value of ethr is overwritten (with a warning message) in the case of a phonon calculation (lphonon flag added). If diago_thr_init is not specified in the input file it is automatically set in setup.f90 (for example in the case of a nscf calculation ethr = tr2 / nelec).
I hope this policy is appropriate for all kind of calculations.

NEB/ removed from makedeps.sh
plotrho: added possibility to have contour lines of various type
A few undefined variables defined (again)

variable wf_collect added to the control namelist.
This logical variable will be used in pw to
collect wave funcions at the end of a parallel run.

- substitution of USE ... with USE ... ONLY ...
- directories and filenames moved to io_files,
common to all codes
- clean up in control_flags

From now on, all new input variables should be added
to this module, and then copied to the code internal
variables in the input.f90 subroutine
The namelists and cards parsers are in :
Modules/read_namelists.f90 and Modules/read_cards.f90
files input_parameters.f90 read_namelists.f90 read_cards.f90
are shared by all codes, while each code has its own version
of input.f90 ( used to copy input values into internals variables ).
EXAMPLE:
suppose you need to add a new input variable called "pippo"
to the namelist control, then:
1) add pippo to the input_parameters.f90 file containing the
namelist control
INTEGER :: pippo = 0
NAMELIST / control / ....., pippo
remember: always set an initialization value!
2) add pippo to the control_default subroutine
( cantained in module read_namelists.f90 )
subroutine control_default( prog )
...
IF( prog == 'PW' ) pippo = 10
...
end subroutine
this routine set the default value for pippo,
that could vary with the code
3) add pippo to the control_bcast subroutine
( cantained in module read_namelists.f90 )
subroutine control_bcast( )
...
call mp_bcast( pippo )
...
end subroutine
4) add pippo to the control_checkin subroutine
( cantained in module read_namelists.f90 )
subroutine control_checking( prog )
...
IF( pippo < 0 ) &
CALL error(' control_checkin ',' variable pippo less than 0 ', 1 )
...
end subroutine
5) Copy the value of pippo in the code internal variables
( file input.f90 )
subroutine iosys()
use input_parameters, only: ...., pippo
use pwcom, only: ....., myvar
...
call read_namelists( 'PW' )
...
myvar = pippo
...
end subroutine

PRIVATE keyword added to all FPMD source files,
variables that have to be known outside the module
are explicitly declared as PUBLIC
CPV:
now CP uses the same input parser as FPMD

io_base: strings with the name of the data sections added to the
restart file, this will allow R/W of data sections in any order
