The purpose of this PR is to facilitate search filtering in ascending/descending order of the keys. If i want to find all the nodes having keys in the range [x, y] in ascending order, then i need to find the node with key below x as the start point. Similarly, if i want to find them in descending order, i need to find the node with key above y as the starting point. Also, I should be able to do it without knowing if x or y are keys in the tree.
