Abstract class for assembling surface-integral parts of vectors in continuum mechanics problems.
For such problems, the matrix has the form [A B1] [B2^T C ] (where often B1=B2 and C=0) and the vector has the form [b1] [b2]
This class adds surface integral components, arising from natural Neumann boundary conditions, to the spatial part of the RHS vector, ie to b1.
