5128126055 arrays: change operator() && for const_view
Changed operator()(int, int...) && for array, and views.

- For const_view and regular type, returns value_type (i.e. a copy).
  NB : does make a copy, not a move. Ok for scalar type. TODO: think for complicated types.
  This allows codes like :
  f(x)(0,0) where f : x-> matrix or const_view
  to be correct in clef expression evaluation.

- For _view : return a value_type &, as before to allow :
    A(....)(0,0) = rhs;
  It is not possible to detect dangling refs in that case at compile time.
  Added a security in TRIQS_ARRAYS_DEBUG mode to detect a dangling ref at run time,
  i.e. the case where the view is "unique" (ref count ==1).
  This would be a quite bad design anyway ...

- also :

 - clean operator[] for vector (old workaround for old gcc...)
 - add IsView flag in ISP impl class, for the impl. of operator() &&

b8d7373177 arrays : fix auto_assign for chains assignment.
A(i_)(om_) << ...
for A an array of gf was not working.
Modified the auto_assign of arrays to handle the case when the object
in the array is itself autoassigned.
Using the model of std::vector adapter for clef, which works.
Also fixed the gf for a little details (gf_impl is usually in the expression tree, not gf).

e82d95d1a8 gf: add C++14 impl of meshes products
-  add c14 include
- the C++14 is lot more readable (due to generic lambda).
- for mesh/product.hpp -> now 2 versions (C++14 and C++11 for temporary
  backward compatibility).

85141350e7 remove warnings in compilation
- triqs & tests now compiles with -Wall on clang (3.2)
Checked on OS X.
Todo : recheck on other compilers.

6820f4865a gf : target_shape_t. change size_t to int
- to avoid narrowing pbs.
- otherwise {n,n}, with n int does not work, which is crazy.

bdac3e159c work on doc for gf, and details.
- little details : code cleaning, clang formatting,  along
with documentation writing for c++ gf.
- separated the mesh in small class for better doc.
- work on documentation : reorganize specialisation, ...

5f7e0989a3 gfs. Rm code introduced only for Krylov QMC

6326c2b4eb gf/clef. Bug fix, and added scalar->matrix reinterpret for blocks
- clef : fix a little bug in storage when evaluating
  (was using the wrong trait to deduce storage type).
- gf : block :
     - added reinterpret_scalar_valued_gf_as_matrix_valued
       for block function
     - cleaned make_block_gf_view_from_vector
     - added make_block_gf_view_from_vectormake_block_gf_view_from_vector_of_cython_proxy
       and changed the cython accordingly because it requires a slightly different syntax.
     - updated tests
- gf : cleaned some template.

579368f24b gf. Clean Fourier
- lazy_fourier and co --> fourier
- ex fourier --> make_gf_from_fourier to make a new gf
- = fourier (g) works only iif lhs is a view, like scalar.
- updated python (commented fourier method).

39edb2f846 [API change] gf : factories -> constructors
- Make more general constructors for the gf.
  gf( mesh, target_shape_t)
- remove the old make_gf for the basic gf.
- 2 var non generic gf removed.
- clean evaluator
- add tensor_valued
- add a simple vertex test.
- clean specialisation
- Fix bug introduced in 1906dc3
- forgot to resize the gf in new version of operator =
- Fix make_singularity in gf.hpp

- clean resize in operator =

- update h5 read/write for block gf
  - changed a bit the general trait to save *all* the gf.
  - allows a more general specialization, then a correct for blocks

- NOT FINISHED : need to save the block indice for python.
  How to reread ?
  Currently it read the blocks names and reconstitute the mesh from it.
  Is it sufficient ?

- clean block constructors

 - block constructors simplest possible : an int for the number of blocks
 - rest in free factories.
 - fixed the generic constructor from GfType for the regular type :
   only enable iif GfType is ImmutableGreenFunction

- multivar. fix linear index in C, and h5 format

  - linear index now correctly flatten in C mode
    (was in fortran mode), using a simple reverse of the tuple in the folding.
  - fix the h5 read write of the multivar fonctions
   in order to write an array on dimension # variables + dim_target
   i.e. without flattening the indices of the meshes.
   Easier for later data analysis, e.g. in Python.

- merge matrix/tensor_valued. improve factories

  - matrix_valued now = tensor_valued<2>
    (simplifies generic code for h5).
  - factories_one_var -> factories : this is the generic case ...
    only a few specialization, code is simpler.

- clef expression call with rvalue for *this
- generalize matrix_proxy to tensor and clean

 - clean exception catch in tests

  - exception catching catch in need in test
    because the silly OS X does not print anything, just "exception occurred".
    Very convenient for the developer...
  - BUT, one MUST add return 1, or the make test will *pass* !!
  - --> systematically replace the catch by a macro TRIQS_CATCH_AND_ABORT
    which return a non zero error code.
   - exception : curry_and_fourier which does not work at this stage
   (mesh incompatible).

- gf: clean draft of gf 2 times
  - comment the python interface for the moment.
  - rm useless tests

f4444f3b49 Revert a wrong fix in expression template for gf
This reverts the part of the commit 1906dc30a5
which introduced modifications in the expr templates of the Green's
functions. The commit had introduced some bugs and this revert
removes them (the expr templates will be taken care of fully in later
commits). This is a temporary fix for issues #18 and #25.

  reverted:   triqs/gfs/data_proxies.hpp
  reverted:   triqs/gfs/gf.hpp
  reverted:   triqs/gfs/gf_expr.hpp

1906dc30a5 Fix expression template for gf & std::vector
- add move semantics in expression template.

for gfs :
- rm descriptor
- Remove data from expr, rewrote assignment
  which now iterates on the mesh, simply.
  RHS models now FunctionOnMesh
- This fix the multiplication bug of gf
- Remove assign_no_resize/assign_with_resize from proxy

2c542647fd clef : new version using lvalues and moving rvalues
- change : all objects are by default
  stored now by reference, not by copy any more.
  Unless the trait force_copy_in_expr is true.
- rvalue refs are moved into the tree
- simplifies a lot the writing of lazy method, objects.
- added a macro for methods
- tests ok. Further check needed to control absence of copies...
- improved documentation

b45045e81c gfs: change the name of the mesh -> gf_mesh for gcc
gcc has a pb because the template mesh<Variable,Opt>
has the name same as the gf mesh method (!).
Clang is fine however on this...

Solution : rename the template mesh<...> to gf_mesh...
Not very elegant, but ok.
