Debian/Ubuntus default "awk" is from 1996 and does not understand
negated character lists (such as every non-comma letter: [^,]). Let's
hope 1996 perl does.

This fixes issue #56

This fixes commit 1cd2bb99, which attempted to plug the memory leak due
to unfreed MPI communicators.

yet another attempt to improve single/double and real/complex
unification more readable

with obvious meaning

for easier comparisons of elpa and mkl, a test case using scalapack
function pdsyevd has been added

This is immensely helpful to diagnose out-of-bounds accesses and memory
leaks.

The MPI communicators were never freed, this created a memory leak for
every elpa_allocate()/elpa_deallocate() cycle.
