d4c96a9d93 gf: minor correction for 2 times, etc...
-> are going to be replaced soon anyway ...

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.

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

one can find the version of the library either from the
c++ or the python (if there is python support).

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.

4f4c697897 separate some tests in c++11 dir for old compilers.

we can skip the tests using new features using recent c++ features.
I.e. compilers below gcc 4.8.1, clang 3.3.
