Overview
Class WrappedStream is the abstract superclass for stream classes that wrap another stream. The basic methods are simple delegated to the wrapped stream. Thus creating a WrappedStream on a CollectionStream would yield an equivalent stream:
arrayStream = [1,2,3].create_stream
arrayStream.to_a => [1,2,3]
Stream::WrappedStream.new(arrayStream).to_a => [1,2,3]
