For volumetric integration: changing nbasis_funcs_per_elem (which later controls weighting). Weighting should be turned off in the volumetric case.
Changing sign of lambda and mu kernels: With a minus sign the derivation is consistent with Tarje's papers (and others) but not with the Fichtner book. The Fichtner book uses a different definition of misfit which I think accounts for the sign difference. The changed sign makes results of waveform modelling using the waveform kernels consistent with axisem solutions for the same model.
Changing valence to 1 for onvertices integration: This might have already been changed in the master version.
