Two of the tree typedefs are already public, such that this is really a 
one line change, no?

I am a little surprised you need access to the vector type
that is used to store accesses. As this is really a trivial change that 
seems to be motivated by another (later) commit, maybe just merge it 
with this commit. This commit will possibly give enough motivation to 
understand why this is needed.
