@carllelandtaylor to address your couple of questions in the code:

1. TODO before merge: does some schema need updating as well? - no, we can leave the tapirlink-related column in the db. it will not be created for new wildbooks, and should not mess up existing legacy tables
2. MassExposeGBIF.java - i agree, this servlet should also go away, as all it does is modify tapirlink values; good call. @TanyaStere42 do you agree? i think then this would cascade to mean also altering: appadmin/admin.jsp (to remove the button) and web.xml to remove the servlet entries.

That seems like minimal scope creep, so I'm good with it if @carllelandtaylor is
