       numbering - global degree of freedom numbering


       The  numbering  class defines methods that furnish global numbering of degrees of freedom.
       This numbering depends upon the degrees of polynoms on elements and  upon  the  continuity
       requirement  at  inter-element  boundary.  For instance the "P1" continuous finite element
       approximation has one degree of freedom per vertice of the mesh, while  its  discontinuous
       counterpart  has  dim(basis) times the number of elements of the mesh, where dim(basis) is
       the size of the local finite element basis.
