VisADLineArray vs. Gridded2DSet

[Leah Heiss <leah@xxxxxxxxxxxxxxxxxx>]

Hello list

Everytime I've mentioned using a VisADLineArray, I've been encouraged to
use a Gridded2DSet.  Could someone please outline for me the pros and cons
of using VisADLineArrays and Gridded2DSets?  Why do Gridded2DSets seem to
be preferred?

Also, is there an example of how to use a VisADLineStripArray?  I've
searched for one, but haven't found any yet.

Thanks

Leah
