/*
In order to reuse the Reader and Writer prototypes in the ClientRequest and
IncomingRequest classes, this function creates a new Reader and Writer class
clones:
ReaderClone1 is created from a Reader and inherits from ClientRequest.
ReaderClone2 is created from a Reader and inherits from IncomingRequest.
WriterClone1 is created from a Writer and inherits from ClientRequest.
WriterClone2 is created from a Writer and inherits from IncomingRequest.

The overall class hierarchy is:
- Client
	GetStream uses ReaderClone1 -> Reader -> ClientRequest -> Request
	PutStream uses WriterClone1 -> Writer -> ClientRequest -> Request
- Server
	GetStream uses ReaderClone2 -> Reader -> IncomingRequest -> Request
	PutStream uses WriterClone2 -> Writer -> IncomingRequest -> Request
