Introducing python script plot.py containing several classes used to
plot matrices stored in block-cyclic distribution as a 1 global matrix.
Docstrings in plot.py should explain the ussage. There are also two
use cases included, both with commented scripts (using classes from
plot.py) and a screenshot. One of the use cases contains also tarball
with data.

Apart from that, a VERY simple module matrix_plot.F90 was created. It
is really simplistic, a more systematic approach towards loging should
be designed. At the moment, matrix output has to be triggered explicitly
in the code by calling a macro SAVE_MATR(event_description, iteration).

- Did not properly handle case when $HOST is not set
- String comparison with "[" is done with a single "="

Because it could be difficult to run the runner directly on miy01,
it is being run on dvl02, but the runner method is "ssh" and the
tests are then build and run on miy01
