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

4d0bb56790 arrays. Clean expression templates
- clean array, matrix, vector expression template
  they take const & of objects, or move && objects
  no more views. -> C++11 modernisation
- Fix a bug in array resize : it was resetting the indexmap
  to C memory layout e.g. for a fortran array
- Fix a bug in read h5 array when not in C order
  (forgot an else, the array was read twice).

0586c77307 add c14 details in std::c14
- to use already a few c14 convenience details :

-> polymorphic std::plus, e.g.
   boost::mpi::reduce (world, A,C, std::c14::plus<>(),0);
this plus determine the type by itself ...
  -> errors on the type can be very cryptic on the gf.

-> add std::c14::make_unique
(equivalent of make_shared for unique_ptr).

b534936589 Fix matrix * alias issue and adapt det_manip
- The previous version of the * operator for matrix was too clever.
It was giving a lazy object and then rewriting C = A *B into gemm (a,A,B,0,C).
The pb was in case of aliasing : when e.g. C = A, or is a part of A.
gemm is not correct that case, and as a result generic code like
a = a *b
may not be correct in matrix case, which is unacceptable.

- So we revert to a simple * operator for matrix
that does immediate computation.
Same thing for matrix* vector

- we also suppress a_x_ty class.

-> for M = a * b,
when M is a matrix, there is no overhead due to move assignment
-> however, when M is a view, there is an additionnal copy.

-Correctness comes first, hence the fix.
However, if one wants more speed and one can guarantee that
there is no aliasing possible, then one has to write a direct gemm call.

-> det_manip class was adapted, since in that case, we can show there
no alias, and we want the speed gain, so the * ops where replaced
by direct blas call (using the array blas interface).

-> also gemm, gemv, ger were overloaded in the case the return
matrix/vector (i.e. last parameter of the function) is not an lvalue,
but a temporary view created on the fly.

072b45ac1c arrays: Remove dim0, dim1, .shape in various matrix object.
Not in the concept, not needed, just an annoyance.

first_dim(A), second_dim(A), get_shape(A) and so on...

017394e17f arrays : add experimental array_const_view
- not completely clear how to
manipulate this alias, in particular when
matching template function
(and portability : require C++11 compiler).

552c440238 arrays : add ConstView to fix const correctness
- A()(0) = 1
will not work any more if A is const, as it should be.

- Introduced the notion of const_view, simply done by a flag
(flag 0, for easy debug)
- changed the slice of ISP to use it (only on C++11 compliant compiler)
- Move BoundCheck Flags to 5.

fc2a620eae arrays: new ref counting and weak views
- improve the mem_block and shared_block.
- the reference counting is now done in the mem_block and shared_block, removing the need of shared_ptr.

- speed tests shows that shared_ptr is very slow (due to thread safety?)
the new version is much better, though not perfect.

- Hence introducing weak views.

- also :
-- clean the guard mechanism for python (to allow returning from python without any python ref left).
-- clean code, add documentation for mem_block
-- remove nan init, which was not working, and corresponding test
-- serialisation of view still unchanged (need to forbid serialization of view ??).

- tests ok, incl. valgrind tests.
