When finding the navigation node to activate for a given url, our navigation
system does not evaluate as a tree of nav nodes.  Instead it evaluates the best
node by checking against a map of nav nodes whose keys are urls.

So,  what if we had a piece of navigation that has an acl preventing the user
from seeing that nav node.  If the nav nodes were evaluated as a tree, than all
of the nodes under that nav node would "inherit" the acl because that entire
section of the tree wouldn't be viewable.  Instead, if a user enters a url that
corresponds to a nav-node under the acled node, they would see an activated node
for the url that they typed, but it would not show the parent node.

The work-around is to add the parent's acl to every child node.

See the screenshot.
