13.93/2.08	Now clausify the problem and encode Horn clauses using encoding 3 of
13.93/2.08	http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
13.93/2.08	We repeatedly replace C & s=t => u=v by the two clauses:
13.93/2.08	  fresh(y, y, x1...xn) = u
13.93/2.08	  C => fresh(s, t, x1...xn) = v
13.93/2.08	where fresh is a fresh function symbol and x1..xn are the free
13.93/2.08	variables of u and v.
13.93/2.08	A predicate p(X) is encoded as p(X)=true (this is sound, because the
13.93/2.08	input problem has no model of domain size 1).
13.93/2.08	
13.93/2.08	The encoding turns the above axioms into the following unit equations and goals:
13.93/2.08
