    AND Constraints

    This constraint handler deals with AND-constraints. These are constraint of the form:

    \[ r = x_1 \wedge x_2 \wedge \dots \wedge x_n \]

    where \(x_i\) is a binary variable for all \(i\). Hence, \(r\) is also of binary type. The variable \(r\) is called resultant and the \(x\)'s operators.
