Example

$> snfusion-gen -h
Usage of snfusion-gen:
  -carbon-ratio int
    	carbon ratio (0-100) giving the initial Carbon/Oxygen composition (default 60)
  -cpu-prof
    	enable CPU profiling
  -n int
    	number of iterations to simulate (default 100000)
  -o string
    	output file name (default "output.csv")
  -seed int
    	seed used for the MonteCarlo (default 1234)
