Copyright (C) 2000 Norman Walsh.
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.
