docs: Return detection of any device in the 'Rich CSS' Tier
  
          The quick way to detect for a tier of devices.
          This method detects for devices which are likely to be capable
          of viewing CSS content optimized for the iPhone,
          but may not necessarily support JavaScript.
          Excludes all iPhone Tier devices.
