MetacatUI

This is really only a major issue when these huge packages are nested tables - the first one will render pretty quickly, but stack up 10+ of those and it does take a while. The UI will render the first table, add it to the page, and then add the "See X more nested tables" link. Once that link is clicked, the other tables will load, either fully or partially. (needs testing)

Fixed - each table is drawn with the minimum number of rows needed (4) and then the other rows are drawn once the Expand link is clicked for that table. This will help with large packages (~1000+) but there may still be performance issues if a package has 100+ nested tables. That can be resolved at a later time since there are no packages like that in Arctic Data or KNB right now.
