27 * The unique element of TAF is that we establish the relationship/mechanism to mutate the Principal derived from
28 * one Authentication mechanism into a trustable Principal of another. The mechanism needs to be decided by system
31 * The Generic "T" is used so that the code used will be very specific for the implementation, enforced by Compiler
33 * This interface will allow differences of trusting Transmutation of Authentication
