williamr@4: A write stream class to externalize data to a Store file.
williamr@4: 
williamr@4: By eventually calling  CFileStreamBuf's write function, it implements the externalization of 
williamr@4: the following data types:
williamr@4: 	TInt8 
williamr@4: 	TUint8 
williamr@4: 	TInt16 
williamr@4: 	TUint16
williamr@4: 	TInt32

williamr@4: 	TInt64
williamr@4: 	TUint64
williamr@4: 	TReal32
williamr@4: 	TReal64
williamr@4: 	TUint8*
williamr@4: 	TUint16*
williamr@4: 	CDes8
williamr@4: 	CDes16
williamr@4: 
williamr@4: After instantiated, it must be opened on a write-moded CDirectFileStore object to externalize data.
williamr@4: It must be closed or destroyed before another stream is opened on the same CDirectFileStore object.
