  ##
  # The Link class. Is a Subclass of String, which lets you treat a Cell that
  # contains a Link just as if it was a String (containing the link's description
  # if there is one or the url with fragment otherwise), but gives you access
  # to the url, fragment and target_frame if you need it.
  #
  #
  # Interesting Attributes
  # #url          :: The Uniform Resource Location this Link points to.
  # #fragment     :: Also called text mark: http://example.com/page.html#fragment
  # #target_frame :: Which frame a Link should be opened in, should also support
  #                  the special frames _blank, _parent, _self and _top.
  # #dos          :: Excel may store a DOS-Filename together with the long
  #                  Filename introduced in VFAT. You probably will not need this,
  #                  but if you do, here is where you can find it.
  class Link < String
    attr_accessor :target_frame, :url, :dos, :fragment

      if @fragment
