[netcdf-java] Examples of featureType="trajectory" files and reading same with toolsUI

Hi,
I'm starting to create some netCDF files using the new discrete sampling geometries in the CF standard. My first example is a trajectory. The header is appended below. However, when I try to read the fie in the latest toolsUI (4.2.26) under the "Trajectory" tab I get a error message that say "Failed to find DataType factory for datatype = TRAJECTORY. I'm looking for clues about my clueless-ness that is leading to this error.
I'd be grateful if others who have created example files of the various discrete sampling geometries would share them with me. Bob Simons, I'm looking at you. ;-) 

Thanks,
Roland
