d3q Code

Implemented a smart mechanism to stop the code immediately if the step end is after the wall limit from input, to save CPU time

Add the possibility of doing a SMA tk calculation without the intrinsic ph-ph scattering, in order to produce the isotopic and casimir linewidth to combine using recompute-sma.m

Many little changes here and there,
most notably, the neutron form factor is more or less reliable (although it only includes Bi Se and Te elements)

Improvements in the Neutron scattering code, inclusion of elastic peak (its norm has to be specified), convolution with experimental width now optional (set to zero to disable it)

Error message clarified

Code taken to level with git version of QE

Herring processes simplified
Two-phonon density of state included, it is not the same thing as JDOS

Doc updated
