+
+   Configuration Class
+   
+   This class provides a configuration file and command line parser
+   for a tree-oriented configuration environment. All runtime configuration
+   is stored in here.
+   
+   Each configuration name is given as a fully scoped string such as
+     Foo::Bar
+   And has associated with it a text string. The Configuration class only
+   provides storage and lookup for this tree, other classes provide
+   configuration file formats (and parsers/emitters if needed).
+
+   Most things can get by quite happily with,
+     cout << _config->Find("Foo::Bar") << endl;
+
+   A special extension, support for ordered lists is provided by using the
+   special syntax, "block::list::" the trailing :: designates the 
+   item as a list. To access the list you must use the tree function on
+   "block::list".
