  """Run problem set.
  
  This script allows to run the handouts. One can either run all problem sets at once or just a
  single one. It is enough to provide a substring for the name.
  
  Examples
  --------
  
  >> run-handout             Run all handouts set.
  
  >> run-handout -n 01      Run handout 01-causal-graphs.
