Provides an interface to accessing and managing configuration files.
This class converts provides an API that takes "section.key-name" style
keys and stores the value associated with it as "key-name" under the
section "section".
This allows for a clean interface wherein the both the section and the
key-name are preserved in an easy to manage form in the configuration files
and the data stored is also nice.
