""" Config is the class to read, load and manipulate the user
 configuration. It read a main cfg (nagios.cfg) and get all informations
 from it. It create objects, make link between them, clean them, and cut
 them into independent parts. The main user of this is Arbiter, but schedulers
 use it too (but far less)"""
