Visiting Nodes

[christian.humer at gmail.com]

Hi Guido,

Node#accept is final because we want to guarantee that all nodes 
annotated with @Child and @Children are visited. Can you give me some 
more details on your use-case? Adding or replacing nodes can be done 
using the Node#replace and Node#insert methods.
