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.

gcc-5 does not compile happy; can work around by renaming lattice peek/poke/transpose/trace templates

42f167ea37 Rework of RNG to use C++11 random. Should work correctly maintaining parallel RNG across

decomposition since the generators are physically indexed and assigned in lexico ordering.
