    This is for example the experiment title, sample name, and user name.

    It also provides several buttons with which the user can change proposal
    info, sample properties, scan environment and setups.

    Options:

    * ``sample_panel`` -- what to show when the user clicks on the "Sample"
      button.  The value must be a panel configuration, e.g. ``panel('...')``
      or ``tabbed(...)``.

      There are several panels that are useful for this:

      - ``nicos.clients.gui.panels.setup_panel.GenericSamplePanel`` -- a panel
        that only shows a single input box for the sample name.
      - ``nicos.clients.gui.panels.setup_panel.TasSamplePanel`` -- a panel that
        also shows input boxes for triple-axis sample properties (such as
        lattice constants).

    * ``popup_proposal_after`` -- if given, the proposal dialog will be opened
      when the daemon has been idle for more than the specified time interval
      (in hours).
    * ``new_exp_panel`` -- class name of the panel which should be opened after
      a new experiment has been started from the proposal info panel.
    * ``finish_exp_panel`` -- class name of the panel which should be opened
      before an experiment is finished from the proposal info panel.
