    10  * OscPacket is the abstract superclass for the various

    11  * kinds of OSC Messages. Its direct subclasses are:

    12  *  OscMessage, OscBundle

    13  *

    14  * Subclasses need to know how to produce a byte array

    15  * in the format specified by the OSC spec (or SuperCollider

    16  * documentation, as the case may be).

    17  *

    18  * This implementation is based on Markus Gaelli and

    19  * Iannis Zannos' OSC implementation in Squeak:
