I should add that indirectLess is a real nested function - not static -
so it could access variables defined in topNIndex. This is why I think
percolateDown can't be TREE_PUBLIC: It calls a function which is nested
in another function and can access variables in that function. So
percolateDown can indirectly access topNIndex's variables and is
therefore, as far as I understand, nested.
