*** Hacks and bug fixes to clean up
* Had to hack assignment to 1.0 in the tests/Grid_gamma test
* norm2l is a hack. figure out syntax error and make this norm2 c.f. tests/Grid_gamma.cc
* Reduce implemention is poor
* Reduce implemention is poor ; need threaded reductions; OMP isn't able to do it for generic objects.
* Bug in SeedFixedIntegers gives same output on each site.
* Bug in RNG with complex numbers ; only filling real values; need helper function -- DONE
* Conformable test in Cshift routines.
*** Functionality
* Implement where to take template scheme.
* Command line args for geometry, simd, etc. layout. Is it necessary to have
user pass these? Is this a QCD specific?
