  version 0.3: Mozzarella

  This script generates a series of dummy data and sends it to all methods, then it generates a series of points
  that will later be plot using gnuplot

  Options:

  --path-tester    -- parse the path of the folder containing the data (F_i_j.txt)
  --params  | -p   -- parameters for stress testers:
                        n     -> The number of companies
                        m     -> The number of crime events
                        isize -> The initial size for experimentations
                        fsize -> The final size for experimentation
                        istep -> The increment of sizes
                        rep   -> The number of repetitions for a each size

  --default | -d   -- automatically run Stress tester with default parameters
  --plot    | -g   -- plot data using gnuplot
  --save    | -s   -- save all output data
  --help    | -h   -- display this help and exit
