Adaptation of VolUniDirShell and VolCylShell jacobian transformations.
VolUniDirShell : R is now referenced with respect to a plane which is parralel to the principal 3D axes, but not necessarily passing trhough the origin of the 3D plane.
VolCylShell : Extension of the cylindrical jacobian transformation along the X and Y axis, and not mandatorily along the Z axis. This new Jacobian Type is valid only 3D, as it is for the Jacobian Type VolUniDirShell.
Some modifications may be required so that Get_Geometry.cpp becomes more coherent to these Jacbian Types and avoid redundancies.
