/** @brief Provide a summary view with to-be-done action descriptions.
*
* Those steps that occur since the previous execution step (e.g. that
* are queued for execution now; in the normal case where there is
* only one execution step, this means everything that the installer
* is going to do) are added to the summary view. Each view step
* can provide one of the following things to display in the summary
* view:
*
* - A string from ViewStep::prettyStatus(), which is formatted
*   and added as a QLabel to the view. Return an empty string
*   from prettyStatus() to avoid this.
* - A QWidget from ViewStep::createSummaryWidget(). This is for
*   complicated displays not suitable for simple text representation.
*   Return a nullptr to avoid this.
*
* If neither a (non-empty) string nor a widget is returned, the
* step is not named in the summary.
