At the moment, LinearConstraintPropagator assumes that the constraint is a LE constraint. We need to handle the other types of constraints (we can also convert GE constraints into LE constraints)
LinearConstraintPropagator can handle equality constraints. We also added a method that converts GE constraints into LE constraints. I think this is good enough.
