nuclear@0: 	A XMLHandle is a class that wraps a node pointer with null checks; this is
nuclear@0: 	an incredibly useful thing. Note that XMLHandle is not part of the TinyXML
nuclear@0: 	DOM structure. It is a separate utility class.
nuclear@0: 
nuclear@0: 	Take an example:
nuclear@0: 	@verbatim
nuclear@0: 	<Document>
nuclear@0: 		<Element attributeA = "valueA">
nuclear@0: 			<Child attributeB = "value1" />
nuclear@0: 			<Child attributeB = "value2" />
nuclear@0: 		</Element>
nuclear@0: 	</Document>
nuclear@0: 	@endverbatim
nuclear@0: 
nuclear@0: 	Assuming you want the value of "attributeB" in the 2nd "Child" element, it's very
nuclear@0: 	easy to write a *lot* of code that looks like:
nuclear@0: 
nuclear@0: 	@verbatim
nuclear@0: 	XMLElement* root = document.FirstChildElement( "Document" );
nuclear@0: 	if ( root )
nuclear@0: 	{
nuclear@0: 		XMLElement* element = root->FirstChildElement( "Element" );
nuclear@0: 		if ( element )
nuclear@0: 		{
nuclear@0: 			XMLElement* child = element->FirstChildElement( "Child" );
nuclear@0: 			if ( child )
nuclear@0: 			{
nuclear@0: 				XMLElement* child2 = child->NextSiblingElement( "Child" );
nuclear@0: 				if ( child2 )
nuclear@0: 				{
nuclear@0: 					// Finally do something useful.
nuclear@0: 	@endverbatim
nuclear@0: 
nuclear@0: 	And that doesn't even cover "else" cases. XMLHandle addresses the verbosity
nuclear@0: 	of such code. A XMLHandle checks for null pointers so it is perfectly safe
nuclear@0: 	and correct to use:
nuclear@0: 
nuclear@0: 	@verbatim
nuclear@0: 	XMLHandle docHandle( &document );
nuclear@0: 	XMLElement* child2 = docHandle.FirstChild( "Document" ).FirstChild( "Element" ).FirstChild().NextSibling().ToElement();
nuclear@0: 	if ( child2 )
nuclear@0: 	{
nuclear@0: 		// do something useful
nuclear@0: 	@endverbatim
nuclear@0: 
nuclear@0: 	Which is MUCH more concise and useful.
nuclear@0: 
nuclear@0: 	It is also safe to copy handles - internally they are nothing more than node pointers.
nuclear@0: 	@verbatim
nuclear@0: 	XMLHandle handleCopy = handle;
nuclear@0: 	@endverbatim
nuclear@0: 
nuclear@0: 	See also XMLConstHandle, which is the same as XMLHandle, but operates on const objects.
