Detailed Description

This class extends the BSTElement class by adding a height and balance factor fields that are useful in AVL tree implementations.

AVL tree elements include a 'height' and a 'balFactor' value, representing the height and balance factor of the AVL tree at that node, respectively. This is useful in representing AVL trees.

AVLTree elements contain a visualizer (ElementVisualizer) object for setting visual attributes (color, shape, opacity, size), necessary for displaying them in a web browser.

AVLTree elements also have a LinkVisualizer object, that is used when they are linked to another element, appropriate for setting link attributes, for instance, between the current element and its left or right child

Parameters

E	the generic parameter object that is part of this element, representing application specific data.
K	is the search key parameter in the AVL tree node; K must be orderable, such as integer, float, string, etc., on which relational operators work.
