minimal xml parser

[Luiz Henrique de Figueiredo <lhf@...>]

I don't know much about XML parsing, but I've come across NunniMCAX
	http://nunnimcax.nunnisoft.ch/en/
and tried it and it seems to be kind of minimal tool that would be useful to
have as a Lua library. I don't know how it compares with expat and other XML
parsers.
