Hack; must bring norm2 into the unary operator list.

ET's are still incomplete.

Benchmark wilson dhop now; 14.6GF on one core, not as fast as SU(3)xSU(3) [23GF] but still not too shabby.
...
Disassembling output shows ugly sequences in the permute sector. Could comparatively benchmark with and without
the if-else structure to see how much I'm losing.
Drops to 9GF as it falls out of cache. Moving to Lebesgue ordering should help there. Substantive progress.

Fixed the stencil sector and Wilson now agrees between stencil based implementation

and the cshift based implementation. Managed to reduce the volume of code in this
sector a little, but consolidation would be good, perhaps taking common
logic out into simple helper functions

Shaken out stencil to the point where I think wilson dslash is correct.

Need to audit code carefully, consolidate between stencil and cshift,
and then benchmark and optimise.

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

a machine. If a "fixedSeed" is used, randoms should be reproducible across different machine
decomposition since the generators are physically indexed and assigned in lexico ordering.
