Hey, I have a quick question on using YAML or saving persistant-data  
types. I have to write a class-level save method for the album class  
that saves an @@album\_list followed by .alb, as well as saving an  
@@tag\_list as tag\_list.tags. How does YAML work, or what is the easiest  
way to do this? What is the idea behind it?
