/*
  Ideas for random sampling:

  Bootstrapping: pull with pu back
  generate a random list of Eventnumbers, induvidual number can occure certain
  times in list, put numbers in List sorted.
  read eventnumbers to process from list
  USE: STL multiset

  sampling: pull random evtn numbers without putting back
  generate a random list with subset of eventlist. pull random number and put
  it in list sorted. if number occurs again skip it. and try next number
  USE: STL set
