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)

make_immutable_array
-------------------------------
**Synopsis**::
template<typename Expr, int ... ph> auto make_immutable_array(Expr const &, clef::pair<ph,range> ...); (1)
template<typename Function> auto make_immutable_array(Function, range ...); (2)
* (1)
From a clef expression, and a range for each placeholder in the expression, build
a lazy object modelling :ref:`ImmutableCuboidArray` concept, with the domain built from the ranges:
Parameters are :
* expr The lazy expression
* i_=R : `i_` is a placeholder, R a range. The `i_=R` produce a clef::pair of `i_` and R , which is the parameter.
* (2)
From a function object and a set of range, build
a lazy object modelling :ref:`ImmutableCuboidArray` concept, with the domain built from the ranges:
**Example**:
