6d58cb2a68 Enable reordering of the loops in the assembler for cache friendly.
This gets in the way of L2 prefetching however. Do next next link in stencil
prefetching.

55f65b81b5 Improvements to the assembler interface that let us move chunks of the
site and s loop into the kernels. This will save on function call overhead and
guarantee L2 prefetching strategy is right since OMP can't distribute the
sub-chunks of work.

34a0fde2ad Fixes to fermion force terms after sign of gamma_mu (0...3) change.
Thought I had already committed these.

Believe I have got the Gparity fermion force working.

* tests/Test_gpdwf_force.cc     -- correctly predicts dS for two flavour pseudofermion
                                   based on a small dt update of U field.

* tests/Test_hmc_EODWFRatio_Gparity.cc -- ran 1 trajectory on 8^4 with dH=0.21.

Need to accumulate a full plaquette log to believe fully which will take some hours of run time.

55cfc89459 * Finished the template/policy style introduction of gparity, except the gparity force terms.
So valence sector looks ok.

FermionOperatorImpl.h provides the policy classes.

Expect HMC will introduce a smearing policy and a fermion representation change policy template
param. Will also probably need multi-precision work.

* HMC is running even-odd and non-checkerboarded (checked 4^4 wilson fermion/wilson gauge).

There appears to be a bug in the multi-level integrator -- <e-dH> passes with single level but
not with multi-level.

In any case there looks to be quite a bit to clean up.

This is the "const det" style implementation that is not appropriate  yet for clover since
it assumes that Mee is indept of the gauge fields. Easily fixed in future.

84a66476ab 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.

4fe110bd07 Two flavour HMC for Wilson/Wilson is conserving energy.
Still to check plaq and <e(-dH)>, but nevertheless this is
progress

d9d4c5916a Elemental force term for Wilson dslash added and tests thereof passing.
Now need to construct pseudofermion two flavour, ratio, one flavour, ratio
action fragments.

3845f267cb 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.
