5267798b48 arrays: a forgotten std::forward in lazy evaluations...
A(i_,0) was not compiling due to a missing forward ...

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).

dd6b996e5d arrays: to_python now raise exception when array is empty
- otherwise it was simply crashing .
- now raise a C++ exception
- adapted cython wrapper to catch it as a python exception

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).

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

072b45ac1c arrays: Remove dim0, dim1, .shape in various matrix object.
Not in the concept, not needed, just an annoyance.
replaced by free functions :
first_dim(A), second_dim(A), get_shape(A) and so on...

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.
