/**
 * @file
 * Provides an Admin UI page for the Workflow Transition labels.
 *
 * Modify the workflow form items so specific workflow transitions
 * can have their own labels which the admin can describe relative
 * to the beginning and ending states.
 * Rather than showing the user a workflow box containing options like
 * "review required" as a state in the workflow, it could say "move to
 * the editing department for grammar review".
