      public class LinearConstraint
      extends Object
      implements Serializable

  A linear constraint for a linear optimization problem.

  A linear constraint has one of the forms:

  - c1x1 + ... cnxn = v
  - c1x1 + ... cnxn <= v
  - c1x1 + ... cnxn >= v
  - l1x1 + ... lnxn + lcst = r1x1 + ... rnxn + rcst
  - l1x1 + ... lnxn + lcst <= r1x1 + ... rnxn + rcst
  - l1x1 + ... lnxn + lcst >= r1x1 + ... rnxn + rcst
  The ci, li or ri are the coefficients of the constraints, the xi are the coordinates of the current point and v is the value of the constraint.
