  ConstantInitializer<T>	A very simple implementation of the ConcurrentInitializer interface which always returns the same object.
  LazyInitializer<T>	This class provides a generic implementation of the lazy initialization pattern.
  MultiBackgroundInitializer	A specialized BackgroundInitializer implementation that can deal with multiple background initialization tasks.
  MultiBackgroundInitializer.MultiBackgroundInitializerResults	A data class for storing the results of the background initialization performed by MultiBackgroundInitializer.
