/**

@internalAll

A write stream class to externalize data to a Store file.

By eventually calling  CFileStreamBuf's write function, it implements the externalization of 

the following data types:

	TInt8 

	TUint8 

	TInt16 

	TUint16

	TInt32 

	TUint32

	TInt64

	TUint64

	TReal32

	TReal64

	TUint8*

	TUint16*

	CDes8

	CDes16

After instantiated, it must be opened on a write-moded CDirectFileStore object to externalize data.

It must be closed or destroyed before another stream is opened on the same CDirectFileStore object.

@see CStoreReadStream
