implements MPQuadraticConstraintOrBuilder
     Quadratic constraints of the form lb <= sum a_i x_i + sum b_ij x_i x_j <= ub,
 where a, b, lb and ub are constants, and x are the model's variables.
 Quadratic matrices that are Positive Semi-Definite, Second-Order Cones or
 rotated Second-Order Cones are always accepted. Other forms may or may not be
 accepted depending on the underlying solver used.
