Class: Dnsruby::Config

Description

 The Config class determines the system configuration for DNS.
 In particular, it determines the nameserver to target queries to.

 It also specifies whether and how the search list and default
 domain should be applied to queries, according to the following
 algorithm :

If the name is absolute, then it is used as is.

If the name is not absolute, then :

   If apply_domain is true, and ndots is greater than the number
   of labels in the name, then the default domain is added to the name.

   If apply_search_list is true, then each member of the search list
   is appended to the name.
