- updated INSTALL documentation
- improved description of kernels src/elpa2_kernels/README_elpa2_kernels.txt
- improved OpenMP builds:
   * usage of OpenMP can now be specified with
     "--enable-openmp" or "--with-openmp"
- improved checks for AVX build (identical to ELPA 2013.08.003):
   * if AVX kernels are specified AVX compilation is tested
   * the option "--with-avx-optimization" automatically updates
     CFLAGS and CXXFLAGS with optimization flags

This is the release of the ELPA_development_version_OpenMP
If OpenMP support is not used, this version has the same
functionality as ELPA_2013.08.

If OpenMP support is used, obviously, a hybrid version of ELPA will be
build.

Allthough this is a release, version ELPA_2013.11 is far from complete!
During the next week optimizations of the OpenMP part will be published,
however, the basic functionality is set by this commit

Based on the ELPA 2013.08.001 a development version for ELPA OpenMP
has been created

This commit releases ELPA version 2013.08

It is identical with the latest commit version 2013.02_BETA, except:

- rename ELPA_2013.02.BETA -> ELPA_2013.08
- update of configure.ac
- remove of src/elpa2.f90_save
- remove of test/Makefile

This version has been tested extensivly, however, there might always
be some bugs.
In case of questions please contact elpa-library@rzg.mpg.de or via
the ELPA forum on http://elpa-lib.fhi-berlin.mpg.de/forum/index.php

Similiar to ELPA_2011.12 this version of ELPA now supports automake.

To the _source_ code of ELPA the following changes had to be made:

-elpa2.F90 now use the create "config-f90.h" file to choose via
 preprocessor switches which kernel was defined by the user

- the SSE-AVX intrinsic kernels of A. Heinecke had to be changed such
  that they support "internal linkage" for the building of a shared
  library.

The following other changes were made to the documentation

- elpa2_kernels/README_elpa2_kernels.txt was updated; the new configure
  targets are explained

- README, INSTALL were updated

To high propability this commit is the last one, before this beta
version	will become an official release

created 2013.02 release

Added OpenMP enhancements to elpa2.f90
Removed MPI-2 dependencies, ELPA should now work with pure MPI-1
Added x86_64 optimized assembler version of the kernels.
Added a straight forward and simple version of the kernels.
Added a description of the kernels.
