 * \defgroup	FactoryGroup Factory
 * \ingroup		FactoriesGroup
 * \brief		Implements a generic object factory.
 * 
 * <i>The Factory Method pattern is an object-oriented design pattern.
 * Like other creational patterns, it deals with the problem of creating objects
 * (products) without specifying the exact class of object that will be created.
 * Factory Method, one of the patterns from the Design Patterns book, handles
 * this problem by defining a separate method for creating the objects, which
 * subclasses can then override to specify the derived type of product that will
 * be created.
 * <br>
 * More generally, the term Factory Method is often used to refer to any method
 * whose main purpose is creation of objects.</i>
 * <div ALIGN="RIGHT"><a href="http://en.wikipedia.org/wiki/Factory_method_pattern">
 * Wikipedia</a></div>
 * 
 * Loki proposes a generic version of the Factory. Here is a typical use.<br>
 * <code><br>
 * 1. Factory< AbstractProduct, int > aFactory;<br>
 * 2. aFactory.Register( 1, createProductNull );<br>
 * 3. aFactory.CreateObject( 1 ); <br>
 * </code><br>
 * <br>
 * - 1. The declaration<br>
 * You want a Factory that produces AbstractProduct.<br>
 * The client will refer to a creation method through an int.<br>
 * - 2.The registration<br>
 * The code that will contribute to the Factory will now need to declare its
 * ProductCreator by registering them into the Factory.<br>
 * A ProductCreator is a just a function that will return the right object. ie <br>
 * <code>
 * Product* createProductNull()<br>             
 * {<br>
 *     return new Product<br>
 * }<br>
 * </code><br>
 * - 3. The use<br>
 * Now the client can create object by calling the Factory's CreateObject method
 * with the right identifier. If the ProductCreator were to have arguments
 * (<i>ie :Product* createProductParm( int a, int b )</i>)
