8a0be42080 Gparity test added; partial implementation -- this is Chris K's doubled lattice only 
and have to regress this with the 2 flavour implementation.

aeb7442d8f 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.

28bdc90908 Sizable improvement in multigrid for unsquared. 
6000 matmuls CG unprec
2000 matmuls CG prec (4000 eo muls)
1050 matmuls PGCR on 16^3 x 32 x 8 m=.01

Substantial effort on timing and logging infrastructure

dc66161f47 Change the SIMD command correctly with precision = double vs. single and 
connect the "Real" default precisoin to a configure flag.
Have RealF, RealD and Real types, where Real is compile target dependent single/double,
RealF is single and RealD is double etc..

35fdba81dd Reorg; moving prec/unprec/schur CG for Wilson and DWF into tests as these are really tests and not benchmarks 
(no performance reports, only convergence test).

2583570e17 Domain wall fermions now invert ; have the basis set up for 
Tanh/Zolo * (Cayley/PartFrac/ContFrac) * (Mobius/Shamir/Wilson)
Approx        Representation               Kernel.

All are done with space-time taking part in checkerboarding, Ls uncheckerboarded

Have only so far tested the Domain Wall limit of mobius, and at that only checked
that it
i)  Inverts
ii) 5dim DW == Ls copies of 4dim D2
iii) MeeInv Mee == 1
iv) Meo+Mee+Moe+Moo == M unprec.
v) MpcDagMpc is hermitan
vi) Mdag is the adjoint of M between stochastic vectors.

That said, the RB schur solve, RB MpcDagMpc solve, Unprec solve
all converge and the true residual becomes small; so pretty good tests.

a75b6f6e78 Large scale change to support 5d fermion formulations. 
Have 5d replicated wilson with 4d gauge working and matrix regressing
to Ls copies of wilson.

a32ac287bb Hand unrolled version of dslash in a separate class. 
Useful to compare; raises Intel compiler from 9GFlop/s to 17.5 Gflops.
                   on ivybridge core. Raises Clang form 14.5 to 17.5

ffc00caea3 Got unpreconditioned conjugate gradient to run and converge on a random (uniform random, 
not even SU(3) for now) gauge field. Convergence history is correctly indepdendent of decomposition
on 1,2,4,8,16 mpi tasks.
Found a couple of simd bugs which required fixed and enhanced the Grid_simd.cc test suite.
Implemented the Mdag, M, MdagM, Meooe Mooee schur type stuff in the wilson dop.
