Partial optimisation; comms in x-dir for red black dslash will be slow as the checker skipping block strided
...
loops are non threadable. Will need to write a kernel for these instead and drive them with a lookup table
to make a look sufficiently simple to thread.

Bug fix for spread out in x (EO) direction.

This is really annoying -- it is very hard to thread the loops with the index
recursion on buffer offset in the red-black case. Must think of a good threading
solution here.

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.

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.
