// Normalisation alert; the g5   project is 1/2(1+-G5) 
//                      the xyzt projects are (1+-Gxyzt)
//
// * xyzt project
//
// This is because this is how the Wilson operator is normally written as
// (m+4r) - \frac{1}{2} D_{hop}
// and / or
// 1 - \frac{1}{2 m+8r} D_{hop} = 1 - kappa D_{hop}
//
// Note that the free, critical hopping parameter kappa is then 1/8 th for r=1.
//
// However, the xyzt 2spin "projectors" are not really projectors because they do not
// square to 1, however the ChiralProjector is a true projector.
//
// For this reason there is NO provision in Grid of a four spinor result from the
// xyzt projectors. They are intended to be used only in combination with "reconstruct" in the
// wilson dirac operator and closely related actions.
//
// I also do NOT provide lattice wide operators of these, since the dirac operator is best implemented
// via Stencils and single site variants will be needed only for the cache friendly high perf dirac operator.
//
// * chiral project
//
// Both four spinor and two spinor result variants are provided.
//
// The four spinor project will be recursively provided to Lattice wide routines, and likely used in 
// the domain wall and mobius implementations.
