Sounds good, thanks Berk.

And if, while that's in the pipeline, can I also request an agumentation
to the documentation -- what is the "TrailId" data that is added to
the pathlines output?  And also, I noticed that the particles output
also has an added data value ("GlyphVector") -- what does that do?

(And there's a typo in the beginning of the documentation -- "much"
should be "must".  Trivial, I know.)
