### Write an implementation of the set class, with associated iterators using a binary search environmental-movement-or-the-gender-eq/">tree.

Write an implementation of the set class, with associated iterators using a binary search tree.

Add to each node a link to the next smallest and next largest node.

Note: To make the code simpler, add a header and tail node which are not part of the binary search tree but help make the linked list part of the code simpler.
