0.2 -> 0.4

• drastic simplifications when writing the ICFP submission

• I'll eventually work those older features back in --- Though it is extremely unlikely, I apologize if you were using them.

0.1 -> 0.2

• improved the treatment of automatically generating algebras
• emphasizing DCOf over DCU
• moved all of the documentation from README to http://code.google.com/p/yoko
• still obsessively tweaking names throughout the library
• improved the treatment of unique constructors
• added SiblingOf and a corresponding superclass constraint to DT
