The name was meant to suggest that it is "iterator over
const_nodes_view". The reason for its existence is convenience:
"xml::const_nodes_view::const_iterator" is redundant and typing it gets
tiresome fast. "xml::const_nodes_view::iterator" removes the noise and
its const-ness is still clear, I think.
