In part of the literature, the convention + is used that the unit cell be the tensor product of the intervale $[-1,1]$, + which is to distinguished properly. + Objects of this class store a multitude of different values needed to do the assemblage steps on real cells rather than on the unit cell. Among these values are the values and gradients of the shape functions at the
