Calculate Eliashberg function from electron-phonon coupling matrix elements interpolated on a triangulated Fermi surface.
a2F integral = double loop on kpoints of the FS triangulation. The ep element calculated for q=k'-k is read from a file. The needed phonons and dynamical matrices calculated by QE are read in and then interpolated as in the method of: F. Giustino et al, Phys. Rev. B 76, 165108 (2007)
