Rework export to use pages or filesystem to improve performance and remove timeouts
currently the XML download works for about 800 plots but not more, VegBranch for 300 plots but not more, because the web-browser times out on the user, or we run out of memory. CVS download rocks, 15,400 plots in less than 2 min.

The download form could use <vegbank:get> and <vegbank:pager> to limit entries in the download, but the trick would be altering the number of plots depending on which download, as some can take more than others. Plus, I'm not sure if there are different methods of getting the plots, using datacart of a list of plot_id (really observation_ids) passed into that form.
