//! To convert an function (curve) polynomial by span in a BSpline. <br>
//! <br>
//!   This class uses the following arguments : <br>
//!   NumCurves :  the number of Polynomial Curves <br>
//!   Continuity:  the requested continuity for the n-dimensional Spline <br>
//!   Dimension :  the dimension of the Spline <br>
//!   MaxDegree :  maximum allowed degree for each composite <br>
//!                polynomial segment. <br>
//!   NumCoeffPerCurve : the number of coefficient per segments = degree - 1 <br>
//!   Coefficients  :  the coefficients organized in the following way <br>
//!       [1..<myNumPolynomials>][1..myMaxDegree +1][1..myDimension] <br>
//!       that is : index [n,d,i] is at slot <br>
//!       (n-1) * (myMaxDegree + 1) * myDimension + (d-1) * myDimension + i <br>
//!  PolynomialIntervals :  nth polynomial represents a polynomial between <br>
//!     myPolynomialIntervals->Value(n,0) and <br>
//!     myPolynomialIntervals->Value(n,1) <br>
//!  TrueIntervals : the nth polynomial has to be mapped linearly to be <br>
//!       defined on the following interval : <br>
//!       myTrueIntervals->Value(n) and myTrueIntervals->Value(n+1) <br>
//!       so that it represent adequatly the function with the <br>
//!       required continuity <br>

  //!  Warning! <br>
//!           Continuity can be at MOST the maximum degree of <br>

//!  TrueIntervals : <br>
//!  this is the true parameterisation for the composite curve <br>
//!  that is : the curve has myContinuity if the nth curve <br>
//!  is parameterized between myTrueIntervals(n) and myTrueIntervals(n+1) <br>

//!  Coefficients have to be the implicit "c form": <br>

//!         The NumberOfCoefficient of an polynome is his degree + 1 <br>
//!  Example: To convert the linear function f(x) = 2*x + 1 on the <br>
//!         domaine [2,5] to BSpline with the bound [-1,1]. Arguments are : <br>
