Input:
   [ h(c,c) -> h(b,f(b)),
     f(h(a,h(c,a))) -> c,
     h(c,b) -> f(a) ]

Make it flat:
   [ f(!cl_1) -> c,
     h(a,!cl_0) -> !cl_1,
     h(c,b) -> f(a),
     h(c,a) -> !cl_0,
     !cr_0 -> f(b),
     h(c,c) -> h(b,!cr_0) ]
Time: 0.000 [s]

Make it Complete (R^):
   [ f(!cl_1) = c,
     h(a,!cl_0) = !cl_1,
     h(c,b) = f(a),
     h(c,a) = !cl_0,
     !cr_0 = f(b),
     h(c,c) = h(b,!cr_0) ]
Time: 0.000 [s]

CPNF:
   [ !cr_0 … f(b),
     !cl_1 … !cl_1,
     a … a,
     !cl_0 … !cl_0,
     c … c,
     b … b ]
Time: 0.000 [s]

Now checking all the pairs in CW...
