1b3c93e22a Rework/global edit to enforce type templating of fermion operators.
Allows multi-precision work and paves the way for alternate BC's and such like
allowing for example G-parity which is important for K pipi programme.
In particular, can drive an extra flavour index into the fermion fields
using template types.

5e370db6c5 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

7678fbd30d PartialFraction Hw with Zolo and Tanh approx converged under CG and passed EO breakdown
and hermiticity tests.

802e94e9ca First pass at continued fraction; solver and even odd decomposition tests pass.
Have to make ContFrac class virtual and derive end non-abstract actions for the particular
cases.

68e26140ee Mobius Caley form, Mobius Zolotarev operators. Pass Even Odd vs unprec test and hermiticity checks
in tests/Grid_any_evenodd.cc; will work on inversion tests shortly.

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.
