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).

91978da6db gfs: mesh product, rename shape method...
- just a renaming for readibility.

1ecec0b933 gfs: Fix bug in imfreq with <0 freq.
- there was a confusion in gf imfreq, in the new case
where freq can be <0 (non real gf, or for product gf).
- index: is the matsubara n, as in the struct matsubara_freq
  index can be >0 or <0
- linear_index : is the shift from the 0. It is always >0.
  Fixed function to compute it.

- Also changed the construction of mesh_point in the generic iterator.
  Before, was constructed with a mesh point of index 0
  Now, added a new constructor on mesh_point_t, just taking the mesh
  which construct the *first* mesh_point.
  Fixed linear, discrete, product accordingly.
  Added to the documentation of the concepts of gf.

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, ...

184274c893 gf : fix bug in mesh_pt_generator
- in the default constructor, do not call the pointer
that may be null.
- appeared only in python (unused in c++), for new matsubara...

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

e0f58aeb62 gf : clean product mesh
- reinterpret array is much simple.
clean old code after check on various compilers

165b44a081 gf: mesh. const_iterator and add cbegin
- for meshes :
clean concept w/ doc, add cbegin, and changed
iterator to const_iterator (more standard name).

44bf1e322a gf product and curry. First draft

- curry in general. To be reread ..
- added some tests.
