Anything if it makes Andreas happy :)

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).

This is a bit cumbersome, as it involves yet another abstract
intermediate type, but necessary due to language limitations.

multiplies. The older (stripe) version also remains, controled

It could happen that ELPA stopped with an error but an exit code "0"
was given, i.e. one could assume everything was fine when it was not!
Now each Fortran "stop" was replaced with "stop 1" to prevent this

This closes issues #48

Due to a bug in the Intel compiler some lines could not be
generalised.

Due to bug in Intel compiler some ifdefs are still necessary

single/double macros introduced in elpa2_trans_ev_band_to_full_complex_template.X90, some macro names unified
