41c2b09184 Shmem comms [NO MPI] target added. The dwf test runs and passes. 
Not really shaken out to my satisfaction though as I want more tests done, so don't declare as working.
But committing my current while I try a few experimentals.

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.

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.

638d2cda11 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..
