2be8df93ad Adding components for even odd decomposed determinant in HMC. 
dH not yet conserved, so something wrong in the eo force code still

0b603225d1 Two flavour HMC for Wilson/Wilson is conserving energy. 
Still to check plaq and <e(-dH)>, but nevertheless this is
progress

f4c74e34d8 Committing incomplete work for parameter file I/O. 
MacroMagic.h is central. Guido and I plan to move
over to generating virtual (XML, JSON, YAML, text, binary) encoding
from macro based system.

cb9da7b371 Temporarily disable gmp dependency simply because Cray XC30's I'm benchmarking 
have a downlevel gmp version that chokes on ::max_align_t where gmp had a
bug as far as I recall.

a8b9109cc8 multishift conjugate gradient added and a strong test: take a diagonal 
but non-identity matrix
l1 0  0  0 ....
0  l2 0  0 ....
0  0  l3 0 ...
.  .   .
.  .   .
.  .   .

And apply the multishift CG to it. Sum the poles and residues.
Insist that this be the same as the exactly taken square root
where l1,l2,l3 >= 0.

0bc004de7c Domain wall fermions now invert ; have the basis set up for 
Tanh/Zolo * (Cayley/PartFrac/ContFrac) * (Mobius/Shamir/Wilson)
Approx        Representation               Kernel.

All are done with space-time taking part in checkerboarding, Ls uncheckerboarded

Have only so far tested the Domain Wall limit of mobius, and at that only checked
that it
i)  Inverts
ii) 5dim DW == Ls copies of 4dim D2
iii) MeeInv Mee == 1
iv) Meo+Mee+Moe+Moo == M unprec.
v) MpcDagMpc is hermitan
vi) Mdag is the adjoint of M between stochastic vectors.

That said, the RB schur solve, RB MpcDagMpc solve, Unprec solve
all converge and the true residual becomes small; so pretty good tests.

a6e1ea216d 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.
