e5878fc459 Remove references to the field 'pneigh'.
Since we now only use the field 'neigh' we don't need pointers stored in
'pneigh' anymore.

f64bbd7e5e Use field neigh to assign and refer to neighbors.
We use the field 'neigh' instead of the field 'pneigh'. The field
'neigh' is of the type of 'blockref' which simplifies the reference to
the neighbors blocks when using MPI. Each reference contains two fields:
cpu and id. In MPI version we cannot use pointers stored in pneigh, but
using blockref structures we can refer to the blocks belonging to other
processors.

c977c610ff Introduce new type of block reference by cpu and id.
The new type 'blockref' is a reference to a block by two integer
numbers, the first points to the cpu that block is running, and the
second one is the block identificator.

1aa75ac2ef Change the leaf field of the block to be logical.
This change should speed up a bit the conditions, since it is faster
than the character comparisons.

9b4abbd520 Added control of refinement/derefinement criterions.
Now we can control the levels of refinement/derefinement criterion from
the config file. The bounds of the domains are stored in the HDF5 files
from now.

b39673bf85 Fixed generation of dx, dy, and dz.
The generation of dx, dy, dz for each level didn't include the base
grid, i.e. they were 2 times larger. Now it is fixed. Also plenty of
minor corrections in different places.

7bc74a39d9 Initial version of refinement/derefinement is working.
It looks like the refining and derefining work more or less, at least
without interrupting the execution. Nevertheless, there are still some
artifacts, like the lack of symmetry after some time or not efficient
derefining of the mesh. This could be cause by the solver, however.

The refinement criterion is computed using pressure now.

Also, some fixes in the boundary code.

e0f211743b Runge-Kutta 2nd order time integration implemented.
In addition, I've done some fixes to the problem initialization, and I
defined new variables igrids, jgrids, kgrids, which specify the
dimensions of the block.

1331044dee More reorganization of the compilation flags.
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.

b8d3c791a1 Store all variables in one array U.
One array U, which is a field in the BLOCK structure, stores all
variables. The number of variables is determined by the nvars parameter.
To access each variable we use variable index now, like idn, imx, imy,
mz, ien, etc.

e75cc33c1f Replaced pointer pfirst with plist. Improved formatting.
I replaced the pointer 'pfirst' pointing to the first element of the
list of blocks with 'plist'. I improved formatting of the informations
printed during the initial mesh generation.

937f96aee2 The initial refinement completed.
I've added 'Z' configuration of the refined block, completed 'N', 'C',
'D', and 'U' configurations. Implemented pointers to the neighbors
correctly. Finally, I've implemented correct initial geometry
generation, by selection of the blocks to refine, their neightbors if of
the lower level, and finally performing the actual refinement.

6abf81e77e Add neighbors pointers.
Neighbors pointers allow for quick access to the neighbors. It means
that we don't need to waste CPU time for searching neighbors by IDs.

ae7b169f7a Problem initialization for refined blocks implemented.
Now, after refining a block, an initialization of children blocks is
performed, as well as the refinement checking.

1cd5504a5a Use pointer array to specify children.
Usage of IDs to find children requires additional work, i.e. looking
through all blocks and comparing their IDs. Instead of IDs we use an
array of pointer for instantenous selection of children.

00690ce344 Block refinement implemented.
Subroutine to refine a selected block has been implemented. This
subroutine creates 4 new blocks, and inserts them before the parent
block. It fills all block arguments like parent, neighbors, leaf flags,
bounds, next and previous pointers, etc.

301619e296 Added a subroutine to check refinement criterion.
A new subroutine 'check_ref' to check the refinement criterion has been
added. I've added also a structure of the initial refinement of the
mesh.

532cdf7b7e Generation of the initial mesh and problem setup.
Implemented the generation of initial blocks in N-configuration with
proper ataching to the list, pointer, neighbors and bounds
initialization, as well as the initial problem setup. Two new files has
been added: mesh.F90 - hadling the adaptive mesh structure, and
problem.F90 - handling the problem initialization.

5c2d0c00c9 New subroutines to allocate/deallocate a block.
The new subroutines take care of allocating and deallocating the space
for one block. Allocation uses dimensions provided by configuration
file. The block dimensions and number of ghost cells have been added to
config.F90 as well.

750fe27334 Added initial versions of config and error modules.
Config module takes care of the configuration file 'config.in'. It
reads the file line by line, parsing each line and extracting the name
and value of parameter. Then it substitutes the parameter with a new
value.

Error module handles error, warning and informative messages. So far it
only prints information on the screen.

There is some improvments for comments formating as well.

the first created block has been added.

847009aafb Initial implementation of block structure.
Block structure has been implemented. Blocks contain pointers to the next
and previous blocks. This easily allows to create block lists. Two
functions are implemented, one for creating initial structure of blocks
with lists, and the second for destroying all blocks from the list.

File 'blocks.F90' has been added to makefile too.
