Grid/TODO

* - BinaryWriter, TextWriter etc...
  - protocol buffers? replace xml

* Stencil operator support                           -----Initial thoughts, trial implementation DONE.
                                                     -----some simple tests that Stencil matches Cshift.
                                                     -----do all permute in comms phase, so that copy permute
						     -----cases move into a buffer.
						     -----allow transform in/out buffers spproj


* CovariantShift support                             -----Use a class to store gauge field? (parallel transport?)

* Consider switch std::vector to boost arrays or something lighter weight
  boost::multi_array<type, 3> A()...    to replace multi1d, multi2d etc..

* How to define simple matrix operations, such as flavour matrices?

* Make the Tensor types and Complex etc... play more nicely.

* Pauli, SU subgroup, etc.. 

* Fourspin, two spin project

* su3 exponentiation & log etc.. [Jamie's code?]
  TaProj

* Parallel MPI2 IO

* rb4d support.

* Check for missing functionality                    - partially audited against QDP++ layout

* Optimise the extract/merge SIMD routines; Azusa??
 - I have collated into single location at least.
 - Need to use _mm_*insert/extract routines.

* Conformable test in Cshift routines.

* QDP++ regression suite and comparative benchmark

AUDITS:

* FIXME audit
* const audit
* Replace vset with a call to merge.; 
* care in Gmerge,Gextract over vset .
* extract / merge extra implementation removal      
* Test infrastructure

   // TODO
   //
   // Base class to share common code between vRealF, VComplexF etc...
  //
   // Unary functions
   // cos,sin, tan, acos, asin, cosh, acosh, tanh, sinh, // Scalar<vReal> only arg
   // exp, log, sqrt, fabs
   //
  // transposeColor, transposeSpin,
   // adjColor, adjSpin,
   //
  // copyMask.
