/*! \brief A class to house all the configuration parameters for NLSR.
 *
 * This class is conceptually a singleton (but not mechanically) which
 * is just a collection of attributes that serve as a
 * separation-of-data for NLSR's configuration variables. NLSR refers
 * to an instance of this class for all its configuration
 * parameters. This object is typically populated by a
 * ConfFileProcessor reading a configuration file.
