chi XML library, stronger than SimpleXML, much easier than libxml++

I developed this XML library because SimpleXML isn't powerful enough, but libxml++ is like a nuclear warhead on crack. So, chi XML library strives to find a happy medium. The library is organized under the namespace chi. You can view the documentation over at the XML docs page. You can use it like this:

XML xml("/my/file/name.xml");
cout << xml.child("some_tag").child("some_other_tag").attribute("attr");

If this XML is given:

<base>
  <some_tag>
    <some_other_tag attr="chi Library is easy!">
    </some_other_tag>
  </some_tag>
</base>

Then the result would be:

Chi Library is easy!
