Grid/lib/qcd/action/fermion/WilsonKernels.h
Peter Boyle 1b3c93e22a Rework/global edit to enforce type templating of fermion operators.
Allows multi-precision work and paves the way for alternate BC's and such like
allowing for example G-parity which is important for K pipi programme.
In particular, can drive an extra flavour index into the fermion fields
using template types.
