Examples of Rosetta abinitio run.

run_examples.sh runs a few tests of the ab initio protocol.
    - Ab initio decoy generation. (RosettaAbintio/scripts/rosettaAB.pl)
    - Ab initio clustering.       (RosettaAbintio/scripts/cluster.pl)
    - Ab initio decoy extraction from a silent file.
                                  (RosettaAbintio/scripts/cluster.pl)
    - Ab initio clustering around an extracted center.
                                  (RosettaAbintio/scripts/cluster.pl)

The results will be generated in a directory "test/".
They can be compared to the "sample_output/" directory.
