/**
 * A duration represents a period of elapsed time, e.g., 4 hours, 23 minutes, 2 seconds.
 * This is differentiated from a point in time (e.g., 4:23:02AM). A meeting that
 * has a duration of 2 hours has that same duration no matter where it was held. A 
 * starting time (point) for that of 2:00PM EST can be unambiguous only if the time
 * zone is added.
 * 
 * <p>
 * Because durations are often used in calculations, both positive and
 * negative values are possible.
 * 
 * <p>
 * Most of the accessor functions for this class will respond with normalized
 * values, where the normalization rules are as follows:
 * <ul>
 *   <li>The seconds and minutes components will have an absolute
 *       value in the range 0..59, inclusive.</li> 
 *   <li>The hours component will have an absolute value in the 
 *       range 0..23, inclusive.</li>
 *   <li>The sign of each component matches the sign of the 
 *       overall duration.  A duration of -61 seconds, for example,
 *       has normalized components of -1 seconds and -1 minutes.</li>
 * </ul>
 * Inputs to the member functions are not, however, required to 
 * be normalized. new Duration(0,0,3,-61) and new Duration(0,0,1,59)
 * are both acceptable (and the resulting Duration objects are equal).
