 The automorphism of a Clifford algebra @code{clifford_prime()} simply
 changes signs of all Clifford units in the expression. The reversion

+of a Clifford algebra @code{clifford_star()} reverses the order of Clifford
 units in any product. Finally the main anti-automorphism
 of a Clifford algebra @code{clifford_bar()} is the composition of the
 previous two, i.e. it makes the reversion and changes signs of all Clifford units
