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.
