-#  Delegation class that delegates even methods defined in super class,
-# which can not be covered with normal method_missing hack.
-#  
-#  Delegator is the abstract delegation class. Need to redefine
-# `__getobj__' method in the subclass.  SimpleDelegator is the 
-# concrete subclass for simple delegation.
-#
-# Usage:
-#   foo = Object.new
-#   foo2 = SimpleDelegator.new(foo)
-#   foo.hash == foo2.hash # => false
-#
-#   Foo = DelegateClass(Array)
-#
-#  class ExtArray<DelegateClass(Array)
-#    ...
-#  end
