SDTS++ Writer Implementation	2:10 PM 8/12/97

	I'll gradually change this format to be more like Jamie's.


1. 	write interface for sio_Writer ABC

	Done.

2. 	interface for sio_8211Writer

	Done.

3. 	implement basic test driver

4. 	sio_8211Writer ctor

5. 		sio_8211Writer::_makeDDR()

6. 		sio_8211Writer::_makeField( sio_8211FieldFormat&, sio_8211DR& )

7. 	sio_8211Writer::put()

8. 		sio_8211Writer::_makeField( sc_Field&, sio_8211DR& )

9. 		sio_8211Writer::_findFieldFormat()

10. 	sio_8211Writer::good()

	This is controversial.  We're still working on resolving error handling,
	which this is a part.
