/** A repository of "shared secrets", which are a mechanism for
    
calling implementation-private methods in another package without
    
using reflection. A package-private class implements a public
    
interface and provides the ability to call package-private methods
    
within that package; the object implementing that interface is
    
provided through a third package to which access is restricted.
    
This framework avoids the primary disadvantage of using reflection
    
for this purpose, namely the loss of compile-time checking. */
