Similar to AbstractFeVolumeIntegralAssembler but is used for constructing finite element objects that are based on SURFACE INTEGRALS, as opposed to volume integrals.
This class assumes that the concrete class only needs to assemble a vector, not a matrix. (Can be extended in the future if needed).
Hence, the (effectively) pure method, that needs to be implemented, is ComputeVectorSurfaceTerm().
The surface terms is assumed to come from Neumann BCs, so only the surface elements containing non-zero Neumann BCs (from the BoundaryConditionsContainer given) are assembled on.
The interface is the same the volume assemblers.
