[albatross-users] Wiki example and related extension: iterate over ctx/session

It might have slipped through the documentation updates (*ahem*) but I
did remember to put it here

   http://www.object-craft.com.au/projects/albatross/albatross/rel-1.10-ctx.html

This means that you could do something very kludgey like this:

        <ul><al-for iter="k" expr="__ctx__._SessionBase__vars.keys()">
           <li><al-value expr="k.value()"/></li>
        </al-for></ul>
