Attribute methods
 r4877@ks:  jeremy | 2006-07-30 20:23:53 -0700
 Factor the attribute#{suffix} methods out of method_missing for easier extension.
 r4878@ks:  jeremy | 2006-07-30 20:42:23 -0700
 More specific method naming, declare many attribute method suffixes, set up default suffixes at module include rather than lazily.
