/**
 * @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 private fields/methods inherited from a class 
 * declared in another library are not visible and do not overload members 
 * from a super class declared in the current library.
