  For any finite abelian group G, the equivariant Gromov-Witten invariants of
C^r/G can be viewed as a certain kind of abelian Hurwitz-Hodge integrals. In
this note, we use Tseng's orbifold quantum Riemann-Roch theorem to express this
kind of abelian Hurwitz-Hodge integrals as a sum over Feynman graphs, where the
weight of each graph is expressed in terms of descendant integrals over moduli
spaces of stable curves and representations of G. This expression will play a
crucial role in the proof of the remodeling conjecture (arXiv:0709.1453,
arXiv:0807.0597) for affine toric Calabi-Yau 3-orbifolds in arXiv:1310.4818.
