tayral edd1ff4529 Restructuring documentation.
A first general restructuration of the doc according to the pattern [tour|tutorial|reference].
In the reference part, objects are documented per topic.
In each topic, [definition|c++|python|hdf5] (not yet implemented)

.. highlight:: c
array, matrix & vector
===========================================
**Synopsis**:
.. code-block:: c
template <typename ValueType, int Rank, ull_t OptionsFlags=0, ull_t TraversalOrder=0> class array;
template <typename ValueType, ull_t OptionsFlags=0, ull_t TraversalOrder=0> class matrix;
template <typename ValueType, ull_t OptionsFlags=0> class vector;
where triqs::ull_t is the type defined by :
.. code-block:: c
typedef unsigned long long ull_t;
* The library provides three basic containers:
* array: general (rectangular) `N`-dimensionnal array; models :ref:`MutableCuboidArray` concept.
* matrix: models the :ref:`MutableMatrix` concept.
* vector: models the :ref:`MutableVector` concept.
and the corresponding view classes: array_view, matrix_view, vector_view (Cf :ref:`partial_views`).
* The matrix and vector are very similar to an array of dimension 2 and 1 respectivily,
except for their algebra. Array form an array algebra, where operation are done element-wise, while matrix and vector
form the usual algebra and vector space of linear algebra.
Template parameters
----------------------------
+-----------------------------------------+-------------------------------+-------------------------------+--------------------------------------+
| Template parameter | Accepted type | Access in the class | Meaning |
+=========================================+===============================+===============================+======================================+
| ValueType | any regular type (typically a | value_type | The type of the element of the array |
| | scalar). | | |
+-----------------------------------------+-------------------------------+-------------------------------+--------------------------------------+
| Rank | int | rank | The rank of the array |
+-----------------------------------------+-------------------------------+-------------------------------+--------------------------------------+
| :ref:`OptionsFlags<arr_templ_par_opt>` | ull_t | opt_flags | Compile time options |
+-----------------------------------------+-------------------------------+-------------------------------+--------------------------------------+
| :ref:`TraversalOrder<arr_templ_par_to>` | ull_t | | Traversal Order for all loops |
+-----------------------------------------+-------------------------------+-------------------------------+--------------------------------------+
NB: Rank is only present for array, since matrix have rank 2 and vector rank 1.
