Usage: get_ind PROBLEM_CHOICE OUT_FILE

Dump ind for problem number PROBLEM_CHOICE to a pickle file of the ind.
Variables are initialized at random.

Details:
 PROBLEM_CHOICE -- int -- problem number
 OUT_FILE -- string -- the file to write the ind to.  Note that this is
   _not_ a state file, but instead a direct pickle of the ind.
