// Explain why no sequence of single and double rotations of a binary tree
// changes the result of an inorder traversal of the tree
//

Single and double rotations are designed to change the height of the tree, 
while not disturbing the order of the tree.  As such the integrity of the tree is
maintained, and the values (although shifted) have not moved in terms of
left most and right most.

As such, an inorder traversal, which represents the tree sequence
from left to right, will remain unchanged.
