/**
* This class connects the Nodes with the Layouts.
* It provides an intelligent iterator over Frames belonging to the Node or
* Node Range. Depending on the purpose of iterating (e.g. to insert other
* Frames before or after the Frames) Master/Follows are recognized and only
* the relevant ones are returned. Repeated table headers are also taken
* into account.
* It's possible to iterate over SectionNodes that are either not directly
* assigned to a SectionFrame or to multiple ones due to nesting.
*
* This class is an interface between the method and a SwClientIter: it
* chooses the right sw::BroadcastingModify depending on the task, creates a SwClientIter
* and filters its iterations depending on the task.
* The task is determined by the choice of class.
*
* 1. Collecting the UpperFrames (so that later RestoreUpperFrames can be called)
* is called by MakeFrames, if there's no PrevNext (before/after we can insert
* the Frames).
* 2. Inserting the Frames before/after which the new Frames of a Node need to
* be inserted, is also called by MakeFrames.
