  // == SHRINK INSERTION =========================

  // == generic for all classes that "personify"

  //    the Personalities/J compiler must insert

  //    these definitions only once at the class

  //    within the hierarchy that is closest to

  //    the root, whose ancestors do NOT personify

  //    anything, but it personifies something.

  //  

  //    In this example, the class that fulfills

  //    these requirements is the Animal class.
