Small question. The app is not separate programs loaded from the command 
line. The main menu loads, then other classes available in other files 
are required and instantiated.

So there are many separate files, but one ruby interpreter. Will 
"$config["XXX"] work through all the programs ?  That seems fairly easy.
Will look into dep inj soon - thanks for the tip.
