/**
 * Class: ExprTree.
 * <br>Description: ExprTree is simply a BinaryNode&lt;String&gt;.  It is used only
 * to simplify the concept of an expresion tree as used in ExprEvaluator.
 * In particular, ExprTree is (normally) the root of the expression tree.
 * It is designed to hide the "complexities" of a BinaryNode&lt;String&gt;.  Actually
 * the most complex part to ordinary user will be the fact that a Expression
 * tree is simply a BinaryNode&lt;String&gt;.
