Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method) ⇒ Object

Provides direct access to constants through methods of the same name This will be used for all constants other than paths

#current_database_for_name(dbname) ⇒ Object

Based on the database shortname and global database path, find the most current version of the required database If dbname corresponds to a folder in the dbroot this function returns the path of the database with an extension appropriate to the database type

If dbname is a full path to a file this tool will first import the file as a temporary database and will then return its full path
