Detailed Description

Implements a MemoryStream wrapper to support GZip compression.

This class is a workaround for how GZipStream needs to be finalised and closes its wrapped stream.

GZipStream compression works by wrapping another stream. The compression stream is not finalised until the GZipStream is closed. Doing so closes the stream wrapped by the zip stream. This makes it impossible to access the written byte count in the memory stream or to reuse the stream.

Most members are simply a pass through to the underlying MemoryStream. However the Close() function flushes the buffer, but leaves the MemoryStream open. In this way, the MemoryStream can continue to be used.
