The plant canopy model has been extended to the prognostic equation for   
the potential temperature and the prognostic equation for the concentration 
of a passive scalar, as proposed by Watanabe (2004) and Shaw and Schumann 
(1992). (prognostic_equations, plant_canopy_model)  

Within a job chain, the number of processors or the virtual processor grid
is now allowed to be changed. This modifies the domain decomposition and
requires that the PEs within a restart job have to know from which file(s) they
have to read their restart data (up to now there is a one to one relation
between the restart files and the PEs, i.e. processor 4 only reads data
from file "_0004"). Informations about the subdomain index limits of all
restart files are now written by PE0 (to file "_0000"). Also, all variables
containing global values which do not depend on the subdomain are written
to file "_0000" only. In a restart run, this file is opened by all PEs to
read these global values and the informations about the subdomain index
limits. Depending on these index limit information it is decided which
restart file(s) has/have to be opened in order to read the complete data
necessary for the current subdomain.

The turbulence recycling method of Kataoka and Mizuno (2002) has been
implemented. A pre-run with smaller model domain can be used to initialize
the real run, in order to spare the CPU time needed to get the turbulence
into a quasi-stationary state (see initializing_actions =
'read_data_for_recycling').

Particle advection adjusted for ocean runs.

New: inflow_turbulence


Changed:
-------
Sharp lateral edges of the plant canopy introduced. Before smaller 
values of the leaf area density than those applied in the prognostic 
equation for the vertical velocity were used in the prognostic equations 
for u and v at the boundaries of the plant_canopy. (init_3d_model)  

-cross_ts_* (read_var_list, write_var_list)
-dopr_time_count, old profil parameters (cross_..., dopr_crossindex,
 profile_***) removed (read_3d_binary, write_3d_binary)

hom_sum moved, volume_flow_area, volume_flow_initial moved from ..._3d_binary
to ..._var_list, hom_sum is now allocated in parin instead of init_3d_model

npex, npey moved from inipar- to d3par-namelist (parin)

myid_char14 removed. This was used since on IBM machines the process rank may
be changed when the final communicator is defined, in order to save the
preliminary processor-id for opening the binary output file for restarts
(unit 14), because otherwise a mismatch occured when reading this file in a
restart job. This mechanism is not needed any more since the subdomain
informations are now contained in file _0000. (parin, check_open)

check_open, init_3d_model, modules, parin, read_var_list, read_3d_binary, write_var_list, write_3d_binary


Errors:
------
Bugfix: add ')' in user_read_restart_data.

The leaf area density is explicitly set to its surface value at k=0. (check_parameters)

Introduce prefix_chr to ensure unique dvrp_file path.
small bugfixes for user_interface sample code (comments):
- initialize ustvst with 0.0 as it is now computed only until nxr and nyn
- two ALLOCATE statements moved from user_read_restart_data back to user_init
- remove 'READ (13) u2_av' statement in user_read_restart_data
Bugfix: remove IF statement in plant_canopy_model_ij (plant_canopy_model)
Bugfix: divide sums(k,8) (e) and sums(k,34) (e*) by ngp_2dh_s_inner(k,sr) 
(like other scalars) (flow_statistics)
Bugfix: dopr_time_count was written on the binary file, which caused that
NetCDF files newly created by restart files (no append of existing files!)
contained uneccessary time levels. (read_3d_binary, write_3d_binary)
Bugfix: extra '*' removed in user_statistics sample code (user_interface)
Bugfix: a stop command was missing in some cases of the parallel branch (local_stop)
Bugfix in volume flow control for non-cyclic boundary conditions (pres)
