Code to Implement
Composite
module Composite should define methods push_component and each_component as well as include the Enumerable module.
push_component
each_component
if a block is given, yield for each component. otherwise return a new Enumerator of the components.
Enumerable
to make use of the methods in the Enumerable module, use alias_method to alias an :each method to the :each_component method.
