strict inequality (over reals) require solving for least-upper/greatest-lower bounds that may coincide with non-strict inequalities (be epsilon stronger). Instead of using the coefficient 'a' to turn the inequality into an equality, add the slack value as a constant.

e844aef896 remove a few more copy constructors, though still not enough to enable the assertion in vector 
I give up for now; there are too many copies left for little return..

baa96909cc mb-skolem for arithmetic with model repair 
The contract is that users of mb-skolem ensure that
interface equalities are preserved (by adding a
sufficient set of disequalities, such as a chain
x1 < x2 < x3 .., to force that solutions for
x_i does not clash).
