Fort13

[skostogl]

This is an attempt to track distributions with fort.13 through sixdesk

The steps are:

• set flag fort13 in sixdeskenv: export flag_fort13=1
• fort.13 is copied in studies, sixtrack_input, chroma and beta jobs
• The angle is locked at 45 deg
• fort.13 is split into jobs according to the number of pairs set at sixdeskenv. The tracking directory will not longer follow the pattern amplitudes->turnse->angles but number of job->turnse->1 angle (TO BE OPTIMIZED)
