IBM Fortran does not support preprocessor directives -D directly. They
have to be passed using -WF, compilation flag. Therefore we add a
variable CPPPREFIX to provide this kind of prefix.

- in this way all flags are controlled from make.config and host
specific files choose the right compilers, options, and libraries,
depending on the chosen flags;
BOUNDARY CONDITIONS
- use TVD interpolation for prolongation of the boundary conditions
CONFIGURATION
- put lower limit for the number of ghost and domain cells
HOST FILES
- host files should not be included in the revision control
INTERPOLATION
- define all arrays as REAL, not REAL(KIND=8) since the precision of
calculations is determined at the compilation stage
- replace j0 and j1 indices with new more obvious il and ir
MESH
- update mesh before calculating new time step
FIXES
- the field neigh of meta blocks structure must use ndims, nsides, and
nfaces variables
BLOCK STRUCTURE
- use pmeta and pdata names for ponters to meta and data blocks,
respectively; this helps reading the code
HOSTS
- turn on DEBUG
The initial block mesh refinement seems to be optimized now. However,
more work in the MPI version is required, e.g. refine blocks on all CPUs
until the number of blocks exceeds some number dependent on the number
of CPUs. From that point refine independently on each CPU.
The initial work on the mesh update has been done too, but the processes
do not exchange block information.
A new 'mpitools' module has been added. This module contains subroutines
to initialize, deinitialize and handle MPI communication. This initial
version can now initialize and deinitialize parallelization. It does not
support full parallelization yet.
Now the source file can use some of the values defined in make files,
like NDIMS. The make files, i.e. makefile, make.default, and host files
are simpler and should be easier to manage.
