Description:
DomWalker is a helper class/framework for writing rewriters that take
the very typical form of walking a DOM tree and manipulating nodes as
you go.
It supports multiple Visitors at the same time, reducing the need for
multiple DOM walks depending on the semantics.
As of this CL the framework isn't used -- it sets up several follow-up
CLs to come.
