Bug in flex_extract v7.0.3 public user mode

[anphi]

I got a message from a user who reported a problem in the public user mode with the following error message:

Traceback (most recent call last):
  File "./submit.py", line 112, in <module>
    main()
  File "./submit.py", line 57, in main
    getMARSdata(args,c)
  File "/media/flexpart/FLEXPART_ROOT_TEMPLATE/scripts/flex_extract_v7.0.3/python/getMARSdata.py", line 111, in getMARSdata
    flexpart.retrieve(server, c.public, dates, times, c.inputdir)

Solved by changing some lines in the FlexpartTools.py file! See code snipet below:

651         attrs['class'] = mclass
652        target = attrs.get('target')
653        if not int(self.public):
654            del attrs['target']
655        print 'target: ', target 

Repository is up to date!
