---Purpose
Creates a rational Bezier surface with a set of poles and a
set of weights.
For the double array the row indice corresponds to the parametric
U direction and the columns indice corresponds to the parametric
V direction.
If all the weights are identical the surface is considered as
non-rational (the tolerance criterion is Resolution from package
gp).
Raised if SurfacePoles and PoleWeights have not the same
Rowlength or have not the same ColLength.
Raised if PoleWeights (i, j) <= Resolution from gp;
Raised if the number of poles of the surface is lower than 2
or greater than MaxDegree + 1 in one of the two directions U or V.
