*** Hacks and bug fixes to clean up and Audits
================================================================
* Base class to share common code between vRealF, VComplexF etc...
* Performance check on Guido's reimplementation strategy
* Bug in SeedFixedIntegers gives same output on each site. -- Think I fixed but NOT checked for sure
* FIXME audit
* const audit
* Replace vset with a call to merge.;
* care in Gmerge,Gextract over vset .
* extract / merge extra implementation removal
* Strong test for norm2, conj and all primitive types. -- tests/Grid_simd.cc is almost there
================================================================
*** New Functionality
================================================================
* Implement where to take template scheme.
* - BinaryWriter, TextWriter etc...
- use protocol buffers? replace xmlReader/Writer ec..
- Binary use htonll, htonl
*** 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.
* 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?
* Strong test for norm2, conj and all primitive types. -- Grid_simd test is almost there
* Expression template engine:
- Audit
- Introduce base clase for Grid Tensors.
- Introduce norm2 unary op.
- Introduce conversion automatic from expression to Lattice<vobj>
-- Audit
-- Norm2(expression) problem: introduce norm2 unary op, or Introduce conversion automatic from expression to Lattice<vobj>
* CovariantShift support -----Use a class to store gauge field? (parallel transport?)

- I have collated into single location at least.
