/**
  Austereo Custom Functionality
    CHANGELOG:
      20080926 - Born, broken out from todayNetwork custom JS.
      20081001 - Updating rotator to update every 3 seconds.
      20081002 - Moved more todayNetwork specific JS to fd.todayNetwork.custom.js.
      20081210 - Moved showControlPanelHeight to fd.todaynetwork.custom.js to allow for scrolling in the music widget (applicable only to Today brands).
      20081215 - Added an anchor tag check on the rotator thumbnail (to resolve which feature div is "active")
