There is only one difference about style of setter methods in a ruby 
script.

We have to write like this with attr_accesor:

  obj.setValue_forKey(value, "aKey")


We can write like this with kvc_accessor:

  obj.aKey = value


When a ruby script do not use setter methods (ex. access from only
Cocoa objects), kvc_accessor equals to attr_accessor.
