Revision 12

-- Minor modification of input/output:

Created procedure "read_logic". Variables of module "logic" are read
by "read_logic" instead of "conf_gcm". Variable "offline" of module
"conf_gcm" is read from namelist instead of "*.def".

Deleted arguments "dtime", "co2_ppm_etat0", "solaire_etat0",
"tabcntr0" and local variables "radpas", "tab_cntrl" of
"phyetat0". "phyetat0" does not read "controle" in "startphy.nc" any
longer. "phyetat0" now reads global attribute "itau_phy" from
"startphy.nc". "phyredem" does not create variable "controle" in
"startphy.nc" any longer. "phyredem" now writes global attribute
"itau_phy" of "startphy.nc". Deleted argument "tabcntr0" of
"printflag". Removed diagnostic messages written by "printflag" for
comparison of the variable "controle" of "startphy.nc" and the
variables read from "*.def" or namelist input.

-- Removing unwanted functionality:

Removed variable "lunout" from module "iniprint", replaced everywhere
by standard output.

Removed case "ocean == 'couple'" in "clmain", "interfsurf_hq" and
"physiq". Removed procedure "interfoce_cpl".

-- Should not change anything at run time:

Automated creation of graphs in documentation. More documentation on
input files.

Converted Fortran files to free format: "phyredem.f90", "printflag.f90".

Split module "clesphy" into "clesphys" and "clesphys2".

Removed variables "conser", "leapf", "forward", "apphys", "apdiss" and
"statcl" from module "logic". Added arguments "conser" to "advect",
"leapf" to "integrd". Added local variables "forward", "leapf",
"apphys", "conser", "apdiss" in "leapfrog".

Added intent attributes.

Deleted arguments "dtime" of "phyredem", "pdtime" of "flxdtdq", "sh"
of "phytrac", "dt" of "yamada".

Deleted local variables "dtime", "co2_ppm_etat0", "solaire_etat0",
"length", "tabcntr0" in "physiq". Replaced all references to "dtime"
by references to "pdtphys".
