  Make tree iterator handle icase equivalence
  
  There is a serious bug in the previous tree iterator implementation.
  If case insensitivity resulted in member elements being equivalent
  to one another, and those member elements were trees, then the
  children of the colliding elements would be processed in sequence
  instead of in a single flattened list.  This meant that the tree
  iterator was not truly acting like a case-insensitive list.
  
  This completely reworks the tree iterator to manage lists with
  case insensitive equivalence classes and advance through the items
  in a unified manner in a single sorted frame.
  
  It is possible that at a future date we might want to update this
  to separate the case insensitive and case sensitive tree iterators
  so that the case sensitive one could be a minimal amount of code
  and the insensitive one would always know what it needed to do
  without checking flags.
  
  But there would be so much shared code between the two, that I'm
  not sure it that's a win.  For now, this gets what we need.
  
  More tests are needed, though.
