-*** 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 ; need threaded reductions; OMP isn't able to do it for generic objects.

-* Bug in SeedFixedIntegers gives same output on each site.
