b331a539b5 New module 'evolution' for time integration.
A new module for the time integration has been added. This module
contains a set of subroutines to perform one step time integration of
each leaf block using 2nd order Runge-Kutta method. More methods can be
added later. Time 't', timestep 'dt' and iteration 'n' have been moved
to this module as well.

ee3cb39fdc Timers counting the execution times added.
A new module called 'timer' has been added. The purpose of this module
is to handle the execution timers of the program or its subtasks, like
initialization, data writing, evolution, etc.

The final summary of the times spent on different task has been added
as well.

5187f4942d We can write some of the block attributes now.
I've implemented storing some of the block attributes in HDF5 files. I
shall complete this by writing down neighbors and children. Then I shall
implement storing data arrays.

cd209ba785 Added a new module to handle the data input/output.
Initial implementation of subroutine 'write_data' to store all data.
This subroutine initially will support only HDF5 file format. The
block structure of the file is not decided yet.

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.

6b4c4693d7 Added parameters for the number of initial blocks.
The parameters iblocks, jblocks, and kblocks specify the number of
initial blocks along each direction. This creates the base domain for
further refinement.

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.

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.
