1d67d29183 Jackson smoothed chebyshev and (untested) completion of force terms
for Cayley, Partial and Cont fraction dwf and overlap.
have even odd and unprec forces.

4cc2ef84d3 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.

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

e3456bf559 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.

8688ff8b3a 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.

3845f267cb 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.

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.
