Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(*args, &block) ⇒ Object

This is being used in order to allow a call to any key in a config file. The key will be treated as a method. Since no such method will exist, the method_missing call will handle finding the key in a file.

Instance Method Details

#determine_data_source ⇒ Object

Determines what data source to use. If this is being called, it means no data source was specified. If an environment variable has been set, that will be used. If no data source can be established, a default data file will be referenced.
