	/// <summary>
	/// Manos config. The config file being loaded is in .ini format that
	/// contains of one or more sections, the main section is what this
	/// API uses. However if wanting to access different sections, one can
	/// go through the Source to access the nini IConfigSource.
	/// 
	/// The configs are loaded from $MANOS_CONFIG first, but if that variable
	/// is not set it will look for manos.config within the current directory.
	/// If neither are found, the config is left empty.
	/// 
	/// Here is an example config:
	/// 
	/// [manos]
	/// database_user = ahall
	/// database_password = temp123
	/// database_name = mydb
	/// database_hostname = localhost
	/// database_type = postgresql
	/// 
	/// Getting the db user is as simple as ManosConfig.GetString("database_user");
	/// </summary>
