 * Hi everyone;
 * I’ve got another database that has a table for categories… for a separate application.
   I was wondering if anyone has ever seen a plugin to load such external categories
   in a sub-panel for selection. I would like to have this cross-referenced data
   so that my external app can pull post data based on these external categories.
 * Could this be done via custom fields?
 * Thanks!
