- Logging: It is now possible to add a reference to a custom logging
  subroutine to the constructor which will be used for logging certain
  events.
- NoFork: The option 'nofork' prevents Cron.pm from creating a new

  process. You can use the 'skip' and 'catch' options to tune the
  behaviour.

  second. 
- Bugfix: Thinks like "*/5" now work like expected
