/**
* \class AvlMel
* \brief AVL tree for elements appearing in multiple trees.
*
* AvlMel allows for an element to simultaneously be in multiple trees without
* the trees interferring with one another. For each tree that the element is
* to appear in, there must be a distinct set of AVL Tree management data that
* can be unambiguously referenced with some base class name. This name
* is passed to the tree as a template parameter and is used in the tree
* algorithms.
*
* The element must use the same key type and value in each tree that it
* appears in. If distinct keys are required, the AvlMelKey structure is
* available.
*
* AvlMel does not assume ownership of elements in the tree. The destructor
* will not delete the elements. If the user wishes to explicitly deallocate
* all the items in the tree the empty() routine is available.
*
* \include ex_avlmel.cpp
