    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.
