/*
* This class implements a pure IStream object
* and can be used for many purposes.
*
* The main reason for implementing this was
* a cleaner implementation of IShellLink which
* needs to be able to load lnks from an IStream
* interface so it was obvious to capsule the file
* access in an IStream to.
