  // other schema, rather than the example, and run happily.

  // The STEPfile is actually an object that manages the relationship
  // between what's instantiated in the instance manager, and how that
  // information gets passed to the outside, e.g., a file on disk.
  
  // First we're going to read in the data from the input STEPfile,
  // and Print it to stdout
  
  // Reading the STEPfile instantiates all the objects in it.
  // The instances get pointers into the InstMgr, and each type
  // and entity gets a pointer into the registry.
