To make it clearer, I'm pretty sure I should be able to just  
interrogate directly "/sites/cofa" to find out what it's NavTreeLevel  
is, but I don't seem to be able to work out from the API what I use  
to do this.

I thought I could just do something like:

CmsJspNavElement cofaRoot = cms.getNavigation 
().getNavigationForResource("/sites/cofa/index.html");
int newRootNav = cofaRoot.getNavTreeLevel();

but I'm obviously passing the wrong kind of parameter to  
getNavigationForResource or Folder or whichever one I try.
