示例1: Resolve

		/// <summary>
		/// Try to resolve the dependency by checking the parameters in 
		/// the model or checking the Kernel for the requested service.
		/// </summary>
		/// <remarks>
		/// The dependency resolver has the following precedence order:
		/// <list type="bullet">
		/// <item><description>
		/// The dependency is checked within the <see cref="CreationContext"/>
		/// </description></item>
		/// <item><description>
		/// The dependency is checked within the <see cref="IHandler"/> instance for the component
		/// </description></item>
		/// <item><description>
		/// The dependency is checked within the registered <see cref="ISubDependencyResolver"/>s
		/// </description></item>
		/// <item><description>
		/// Finally the resolver tries the normal flow 
		/// which is using the configuration
		/// or other component to satisfy the dependency
		/// </description></item>
		/// </list>
		/// </remarks>
		/// <param name="context">Creation context, which is a resolver itself</param>
		/// <param name="contextHandlerResolver">Parent resolver</param>
		/// <param name="model">Model of the component that is requesting the dependency</param>
		/// <param name="dependency">The dependency model</param>
