-/// \brief Provides a way to create Entity objects from their class
-/// name.
-///
-/// The dynamic graph frameworks relies on entities (see Entity)
-/// which defines atomic processing units. This class provides a
-/// robust way to enumerate and instantiate these entities.
-/// Each entity has a name (its type name) and can be instantiated.
-/// Each instance also has a name.
-///
-/// For instance one can define a C++ class called MyEntity which
-/// inherits from dynamicgraph::Entity. This type can be registered
-/// into the factory to teach the framework that:
-/// - this entity exists
-/// - this entity can be instantiated (and how to instantiate it).
-///
-/// To achieve this, one must pass an entity name and a function pointer.
-///
-/// The entity name will identify the class <b>at run-time</b>
-/// (be careful: this may not be equivalent to the C++ class name
-/// even if it is recommended to do so).
-///
-/// The function pointer must point on a function taking a string as
-/// input and returning an instance of the Entity (the concrete
-/// subclass, not directly the upper Entity class).
-///
-/// The instances returned by this function <b>must</b> be
-/// dynamically allocated and the caller <b>must</b> get the
-/// ownership of the instance (i.e. it will free it when required).
-///
-/// To finish, please note that the instance name indicates to the
-/// entity how the instance itself is called at run-time.  This name
-/// does not need to be unique and no check is done on it.  It is
-/// the caller responsibility to make sure that the instance name is
-/// appropriate and to check for uniqueness if required.
-///
-///
-/// This class is a singleton. The rationale is that each
-/// unique name must identify a unique Entity. The use of a single
-/// instance of this class enforces this behavior, instantiating one
-/// yourself would break this property.
