/**
 * Find the next step from the challenge.
 * This is an important step in the generic authentication flow. After the responding to a challenge,
 * the results are analyzed here to determine the next step in the authentication process.
 * Like all other methods in this SDK, this is designed to work with Continuation objects.
 * This method returns a {@link Runnable} with the code to be executed, for the next step, to the invoking Continuation.
 * The possible steps are/*from ww  w .jav  a2 s . c  o  m*/
 *  1) Authentication was successful and we have the tokens, in this case we call {@code onSuccess()} to return the tokens.
 *  2) User password is required, an AuthenticationContinuation is created.
 *  3) MFA validation is required, a MultiFactorAuthenticationContinuation object is created.
 *  4) Other generic challenge, the challenge details are passed to the user.
 *
 * @param challenge                 REQUIRED: Current challenge details, {@link RespondToAuthChallengeResult}.
 * @param callback                  REQUIRED: {@link AuthenticationDetails} callback.
 * @param runInBackground           REQUIRED: Boolean to indicate the current threading.
 * @return {@link Runnable} for the next step in user authentication.
