Hmmm, unfortunately, the Java netcdf API doesnt allow you to
incrementally update the Schema; the Schema in a NetcdfFile is
considered immutable.
Kinda lame, but I think thats the way it is. You could 1) read the data
twice, accumulating the scheme on the first pass, or 2) write seperate
files for each Variable, then merge at the end. Probably some other
options, but you can probably figure them out based on your situation.
