Syntax
public virtual Tree Add(Tree newNode, int cmp)Remarks
On adding a node to a tree, if it already exists, and if
Tree#duplicates() returns false, #isDuplicateOf() will be
called. The added node can then be asked for the node that
prevails in the tree using #duplicateOrThis(). This mechanism
allows doing find() and add() in one run.
