 * addition, it contains a getter for every public type created by one of its
 * fragments, each of which forwards to a getter in the corresponding
 * fragment.  In addition to being the injector's public interface, these
 * getters are used by each fragment of the injector to retrieve objects
 * created by other fragments.
