It builds up a link to the page, including all relevant state information 
of the tree. You need all three variables (tree-s, tree-e and tree-c) 
because they represent the state of the tree on click ago, before 
displaying the tree. Complicated, but it works. Tree-s is the state of the 
tree before expanding or collapsing any branches, tree-e and tree-c are 
modifications to the tree, specifying collapsing or expanding branches. It 
could be that this URL can be simplified, I haven't experimented enough 
with this yet.

Previous/Next can be a bit tricky, especially at the boundaries of the 
chapters (we have to figure out what the last article in the previous 
chapter is; and  _if_ there is any previous chapter...)

I think I can solve this with a DTML Method in the starting folder that, 
like the zb_all_view method, uses recursion and acquisition to determine 
the full list of documents, and compiles a list from which we can determine 
a previous/next link.

I'll get back to you on this.
