BilateralLagrangianConstraint
-----------------------------

Context: Sofa.Component.Constraint.Lagrangian.Model

BilateralLagrangianConstraint defining an holonomic equality constraint (attachment)

Data:
 - name : object name
 - printLog : if true, emits extra messages at runtime.
 - tags : list of the subsets the objet belongs to
 - bbox : this object bounding box
 - componentState : The state of the component among (Dirty, Valid, Undefined, Loading, Invalid).
 - listening : if true, handle the events, otherwise ignore the events
 - group : ID of the group containing this constraint. This ID is used to specify which constraints are solved by which solver, by specifying in each solver which groups of constraints it should handle.
 - constraintIndex : Constraint index (first index in the right hand term resolution vector)
 - endTime : The constraint stops acting after the given value.
Use a negative value for infinite constraints
 - first_point : index of the constraint on the first model
 - second_point : index of the constraint on the second model
 - rest_vector : Relative position to maintain between attached points (optional)
 - numericalTolerance : a real value specifying the tolerance during the constraint solving. (optional, default=0.0001)
 - activate : control constraint activation (true by default)
 - keepOrientationDifference : keep the initial difference in orientation (only for rigids)
