/*
   This program reads in the dimensions of a box and then constructs
   a Box3 object that encapsulates the data for the box.

   Since the data fields of an object are private, this program uses
   "accessor methods" (i.e., get methods) to retrive data from the object.

   This program makes use of the fact that Box3 objects can compute their
   own volume and "length plus girth".
