[Nexus] NeXus-Design

[Mark Koennecke]

High,

I have added three new discussion topics in the new NeXus mediawiki 
under the Design section.
* Indirect geometry TOF
* Coordinate systems
* Double linking.
Please comment.

The NeXus mediawiki is at: http://www.nexus.anl.gov/mediawiki

                          Best Regards,

                                      Mark Koennecke
