/**

Implements an iterator or filtered iterator for a tree.  

This classes behaves in two very different ways, depending on the

template parameter.

1)  RXmlEngNodeList<TXmlEngNode>

Through template specialization, this becomes an alias for RXmlEngNodeListImpl.

The RXmlEngNodeListImpl::OpenL() methods control which nodes are included in

the iterator.  It is possible to iterate across all node types or only a single

type.  It is possible to iterate only over nodes within a specific namespace.

It is also possible to iterate over nodes with the same name.

RXmlEngNodeListImpl should not be used directly.

@see RXmlEngNodeListImpl

2)  RXmlEngNodeList<X> where X is not TXmlEngNode

As the OpenL() methods of this class are private, this class cannot be opened

except by friend classes TXmlEngNode and TXmlEngElement.  As such, this form

should not be used.
