5ef42add2d Changes to remove warnings under icc; disambiguate AVX512 from IMCI correctly 
and drop swizzles in AVX512. Don't know why these compiled.

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.

755dca9533 Added ForceGradient integrator. dH dropped so seems to work. Will only 
believe it is right once I have pulled a dt^4 error scaling plot out.

29fd004d54 Unified integrator and integrator algorithm into virtual class used as a policy for the 
HMC.

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.

dc814f30da Binary IO file for generic Grid array parallel I/O. 
Number of IO MPI tasks can be varied by selecting which
dimensions use parallel IO and which dimensions use Serial send to boss
I/O.

Thus can neck down from, say 1024 nodes = 4x4x8x8 to {1,8,32,64,128,256,1024} nodes
doing the I/O.

Interpolates nicely between ALL nodes write their data, a single boss per time-plane
in processor space [old UKQCD fortran code did this], and a single node doing all I/O.

Not sure I have the transfer sizes big enough and am not overly convinced fstream
is guaranteed to not give buffer inconsistencies unless I set streambuf size to zero.

Practically it has worked on 8 tasks, 2x1x2x2 writing /cloning NERSC configurations
on my MacOS + OpenMPI and Clang environment.

It is VERY easy to switch to pwrite at a later date, and also easy to send x-strips around from
each node in order to gather bigger chunks at the syscall level.

That would push us up to the circa 8x 18*4*8 == 4KB size write chunk, and by taking, say, x/y non
parallel we get to 16MB contiguous chunks written in multi 4KB transactions
per IOnode in 64^3 lattices for configuration I/O.

I suspect this is fine for system performance.
