LazyKit: tools for XML processing

[Jay Carlson <nop@...>]

I've uploaded LazyKit, a set of tools (and documentation) for processing 
XML in Lua.  Wiki page at http://lua-users.org/wiki/LazyKit .

A quick summary of contents:

XmlTree: a rough specification of an XML representation
LxpTree: an obvious tree builder, using LuaExpat
LazyTree: trees built on demand
ConsumingXml: a description of consuming iterators and benefits
XmlIter: iterators over trees, and a generic XML switch filter
XmlView: convenience views on trees

The package also includes a quick hack of an XML generator from trees, 
and iostring/ciostring.

I'm not deeply committed to names, packaging arrangements, semantics, 
etc.  I'm hoping to spur discussion.  (Although if nobody wants to talk 
about it, I'll just quietly use these myself.)
