/**
* \class AvlTree
* \brief Basic AVL tree.
*
* AvlTree is the standard by-structure AVL tree. To use this structure the
* user must define an element type and give it the necessary properties. At
* the very least it must have a getKey() function that will be used to
* compare the relative ordering of elements and tree management data
* necessary for the AVL algorithm. An element type can acquire the management
* data by inheriting the AvlTreeEl class.
*
* AvlTree does not presume to manage the allocation of elements in the tree.
* The destructor will not delete the items in the tree, instead the elements
* must be explicitly de-allocated by the user if necessary and when it is
* safe to do so. The empty() routine will traverse the tree and delete all
* items.
*
* Since the tree does not manage the elements, it can contain elements that
* are allocated statically or that are part of another data structure.
*
