/**  
 * The <code>ZeroVectorException</code> exception is thrown by
 * utilities that perform calculations on vectors. If a particular
 * operation is undefined for the zero vector, a
 * <code>ZeroVectorException</code> exception is thrown. The motivation
 * for this class (as opposed to using a standard <code>ArithmeticException</code>)
 * is to allow filtering based on the type of the exception.
