class_docstr: Object returned by the timeit magic with info about the run.
  
  Contains the following attributes :
  
  loops: (int) number of loops done per measurement
  repeat: (int) number of times the measurement has been repeated
  best: (float) best execution time / number
  all_runs: (list of float) execution time of each run (in s)
  compile_time: (float) time of statement compilation (s)
code: def _repr_pretty_(self, p, cycle):
      if self.loops == 1:  # No s at "loops" if only one loop
