Olivier Parcollet 3fe400d34c doc : split c++ code from rst
- examples split from the rst file using a python script (split_code).
- Final result for the doc is unchanged.
- examples are compiled and tested with the other tests.
- examples' code have been clang-formatted, with triqs style.
- doc compiles much faster, and with the same options as the rest of the
  test.
- examples are added as tests, so they are run by make test, as simple C
  tests.
- done for the tutorials and the reference.
- autocompile removed (changed into triqs_example directive).
- add triqs_example :
   - make a literal include of the source code.
   - runs the compiled example
   - add, as before, the result to the source code in the doc.
- added the script split_code, used to make the changes automatically,
  maybe for later reuse. (in _tools)

.. _Shape:
Shape & dimensions
==================================
**Synopsis**:
.. code-block:: c
template <ImmutableArray A> mini_vector<size_t,R> get_shape(A const &); // R is the rank of A
template<ImmutableArray A> size_t first_dim (A const & x);
template<ImmutableArray A> size_t second_dim (A const & x);
template<ImmutableArray A> size_t third_dim (A const & x);
template<ImmutableArray A> size_t fourth_dim (A const & x);
template<ImmutableArray A> size_t fifth_dim (A const & x);
template<ImmutableArray A> size_t sixth_dim (A const & x);
template<ImmutableArray A> size_t seventh_dim (A const & x);
The shape and dimensions of any object modeling :ref:`ImmutableCuboidArray` is obtained using get_shape and xxx_dim functions :
.. triqs_example:: ./shape_0.cpp
