A Comparison object applies a comparison operator to its
terms in order to prove itself.
The functor of a comparison must be one of the strings, "<",
">", "<=", ">=", "=", or "!=", indicating comparison this
object will perform during a proof. Any other functor will
cause the comparison to always be false.
Here is an example of a comparison:
Atom alpha = new Atom("alpha");
Atom beta = new Atom("beta");
Comparison c = new Comparison("<=", alpha, beta);
System.out.println(c + ", " + c.canFindNextProof());
This prints out:
<=(alpha, beta), true
