/**
* \class AvlMelKey
* \brief AVL tree for elements appearing in multiple trees with different keys.
*
* AvlMelKey is similar to AvlMel, except that an additional template
* parameter, BaseKey, is provided for resolving ambiguous references to
* getKey(). This means that if an element is stored in multiple trees, each
* tree can use a different key for ordering the elements in it. Using
* AvlMelKey an array of data structures can be indexed with an O(log(n))
* search on two or more of the values contained within it and without
* allocating any additional data.
*
* AvlMelKey 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_avlmelkey.cpp
