class MultiLine from AppDef
---Purpose: This class describes the organized set of points used in the
-- approximations. A MultiLine is composed of n
-- MultiPointConstraints.
-- The approximation of the MultiLine will be done in the order
-- of the given n MultiPointConstraints.
--
--
-- Example of a MultiLine composed of MultiPointConstraints:
--
-- P1______P2_____P3______P4________........_____PNbMult
--
-- Q1______Q2_____Q3______Q4________........_____QNbMult
-- . .
-- . .
-- . .
-- R1______R2_____R3______R4________........_____RNbMult
--
--
-- Pi, Qi, ..., Ri are points of dimension 2 or 3.
--
-- (P1, Q1, ...R1), ...(Pn, Qn, ...Rn) n= 1,...NbMult are
-- MultiPointConstraints.
-- There are NbPoints points in each MultiPointConstraint.

---Purpose: given the number NbMult of MultiPointConstraints of this
-- MultiLine , it initializes all the fields.SetValue must be
-- called in order for the values of the multipoint
-- constraint to be taken into account.
-- An exception is raised if NbMult < 0.

---Purpose: The MultiLine constructed will have one line of

-- MultiPoints are different.
