Fixed bug impacting when a single reach makes upa  segment
Made external config file (xml style) for input of flags and options.
tried rotating about lower-left model corner rather than origin. Still offset problems.
Added segment and reach as fields to the shapefile output.
Finally sorted out the rotation business. Still a problem with projection in ARC but not a part of this code
Removed a couple crufty files
