* Move seal barrier type field from Access to autoSeal struct. Remove method Access.SetType(), which was only being used by a single test, and which can use the name option of NewTestSeal() to specify the type. * Change method signatures of Access to match those of Wrapper. * Turn seal.Access struct into an interface. * Tweak Access implementation. Change `access` struct to have a field of type wrapping.Wrapper, rather than extending it. * Add method Seal.GetShamirWrapper(). Add method Seal.GetShamirWrapper() for use by code that need to perform Shamir-specific operations.
