/// @assertion Dart supports two levels of privacy: public and private. 
/// A declaration is private iff its name is private, otherwise it is public.
/// A name q is private iff any one of the identifiers that comprise q is 
/// private, otherwise it is public.
/// An identifier is private iff it begins with an underscore (the _ character) 
/// otherwise it is public.
/// A declaration m is accessible to library L if m is declared in L or if m is 
/// public.
/// @description Checks that various private class members are perfectly 
/// accessible to a subclass that is declared in the same script.
