 * OscPacket is the abstract superclass for the various

 *  OscMessage, OscBundle
 *
 * Subclasses need to know how to produce a byte array
 * in the format specified by the OSC spec (or SuperCollider
 * documentation, as the case may be).
 *
 * This implementation is based on Markus Gaelli and
 * Iannis Zannos' OSC implementation in Squeak:
