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;
