8e161152e4 MultiRHS solver improvements with slice operations moved into lattice and sped up.
Block solver requires a lot of performance work.

841a37f941 Fix to WilsonCompressor that fixes a bug in comms phase due to the sign change on gamma
matrix in hopping term.
Add logging of time spent in CG.

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.

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

d1afebf71e Sizable improvement in multigrid for unsquared.
6000 matmuls CG unprec
2000 matmuls CG prec (4000 eo muls)
1050 matmuls PGCR on 16^3 x 32 x 8 m=.01

Substantial effort on timing and logging infrastructure

4dba8522a1 Got unpreconditioned conjugate gradient to run and converge on a random (uniform random,
not even SU(3) for now) gauge field. Convergence history is correctly indepdendent of decomposition
on 1,2,4,8,16 mpi tasks.
Found a couple of simd bugs which required fixed and enhanced the Grid_simd.cc test suite.
Implemented the Mdag, M, MdagM, Meooe Mooee schur type stuff in the wilson dop.

11cb3e9a01 Getting closer to having a wilson solver... introducing a first and untested
cut at Conjugate gradient. Also copied in Remez, Zolotarev, Chebyshev from
Mike Clark, Tony Kennedy and my BFM package respectively since we know we will
need these. I wanted the structure of

algorithms/approx
algorithms/iterative

etc.. to start taking shape.
