    This class provides a Saxon 6.* implementation to scan the column widths in a result tree fragment.

    The general design is this: the stylesheets construct a result tree fragment for some colgroup environment. That result tree fragment is "replayed" through the ColumnUpdateEmitter; the ColumnUpdateEmitter watches the cols go by and extracts the column widths that it sees. These widths are then made available.
