docs: Fetch the options for possible files to
          load replace etc for the given element.
  
          Options from which to choose a file to load or replace.
          The options are a :class:`jukeboxcore.gui.treemodel.TreeModel`
          with :class:`jukeboxcore.filesys.TaskFileInfo` as leafes internal data.
          I explicitly say leafes because the options might be sorted in a tree like strucure.
          So the user could first select a task and then the apropriate release.
          You can take the model and display it to the user so he can select a file.
  
          :param element: The element for which the options should be fetched.
          :type element: :class:`jukeboxcore.djadapter.models.Asset` | :class:`jukeboxcore.djadapter.models.Shot`
          :returns: the option model and a list with all TaskFileInfos
          :rtype: ( :class:`jukeboxcore.gui.treemodel.TreeModel`, list of :class:`TaskFileInfo` )
          :raises: None
