//! A topological attribute can be seen as a hook
//! into the topological structure. To this hook,
//! data can be attached and references defined.
//! It is used for keeping and access to
//! topological objects and their evolution. All
//! topological objects are stored in the one
//! user-protected TNaming_UsedShapes
//! attribute at the root label of the data
//! framework. This attribute contains map with all
//! topological shapes, used in this document.
//! To all other labels TNaming_NamedShape
//! attribute can be added. This attribute contains
//! references (hooks) to shapes from the
//! TNaming_UsedShapes attribute and evolution
//! of these shapes. TNaming_NamedShape
//! attribute contains a set of pairs of hooks: old
//! shape and new shape (see the figure below).
//! It allows not only get the topological shapes by
//! the labels, but also trace evolution of the
//! shapes and correctly resolve dependent
//! shapes by the changed one.
//! If shape is just-created, then the old shape for
//! accorded named shape is an empty shape. If
//! a shape is deleted, then the new shape in this named shape is empty.
//! Different algorithms may dispose sub-shapes
//! of the result shape at the individual label depending on necessity:
//! -  If a sub-shape must have some extra attributes (material of
//! each face or color of each edge). In this case a specific sub-shape is
//! placed to the separate label (usually, sub-label of the result shape label)
//! with all attributes of this sub-shape.
//! -  If topological naming is needed, a necessary and sufficient
//! (for selected sub-shapes identification) set of sub-shapes is
//! placed to the child labels of the result
//! shape label. As usual, as far as basic solids and closed shells are
//! concerned, all faces of the shape are disposed. Edges and vertices
//! sub-shapes can be identified as intersection of contiguous faces.
//! Modified/generated shapes may be placed to one named shape and
//! identified as this named shape and source named shape that also can be
//! identified with used algorithms.
//! TNaming_NamedShape may contain a few
//! pairs of hooks with the same evolution. In this
//! case topology shape, which belongs to the
//! named shape, is a compound of new shapes.
//! The data model contains both the topology
//! and the hooks, and functions handle both
//! topological entities and hooks. Consider the
//! case of a box function, which creates a solid
//! with six faces and six hooks. Each hook is
//! attached to a face. If you want, you can also
//! have this function create hooks for edges and
//! vertices as well as for faces. For the sake of
//! simplicity though, let's limit the example.
//! Not all functions can define explicit hooks for
//! all topological entities they create, but all
//! topological entities can be turned into hooks
//! when necessary. This is where topological naming is necessary.
