5a80930dd2 Charge conjugation boundary conditions for gauge fields implemented as a policy
class, changing the nature of covariant Cshifts used in
plaquettes, rectangles and staples.

As a result same code is used for the plaq and rect action independent of the BC type.

Should probably isolate the BC in a separate class that Gimpl takes as a template param.
Do the same with smearing policies.

This would then allow composition of BC with smearing etc....

08edbb5cbe HMC bit repro across checkpoints. Fixed parallel RNG issue with threading.
Conclusion: c++11 distributions not thread safe and must us distinct dist as well as distinct engine
per site. Makes sense when you think of box muller. Also added a reset of dist on fill to ensure
repro across checkpoints.

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.

638d6675ee Tested rms dH is ~ dt^4 numerically, so believe the ForceGradient is correct now.
Paranoia makes me want to diddle with the FG step to ensure dt^2 reappears.

aa52fdadcc Global edit on HMC sector -- making GaugeField a template parameter and
preparing to pass integrator, smearing, bc's as policy classes to hmc.

Propose to unify "integrator" and integrator algorithm in a base/derived
way to override step. Want to read through ForceGradient to ensure
that abstraction covers the force gradient case.

76d752585b Started a tidy up in the HMC sector. Now comfortable with the two level integrators;
to a little figure out what Guido had done & why -- but there is a neat saving of force
evaluations across the nesting time boundary making use of linearity of the leapP in dt.

I cleaned up the printing, reduced the volume of code, in the process sharing printing
between all integrators. Placed an assert that the total integration time for all integrators
must match at end of trajectory.

Have now verified e-dH = 1 for nested integrators in Wilson/Wilson runs with both
Omelyan and with Leapfrog so substantial confidence gained.
