so,i think it's better to make the CCNode object have the virtual bool init() function~~~~

hi,all:
i think it’s better to add virtual bool init() function to the CCNode,so when i create a new object,i can call the init() function by myself,and then the init()function will be rewrite by suboject,and do what i want it do.
i write the UILoader model recently. and i must create the ui layout by the layout files. so i must create the object(such as Label,Sprite,Layer…) by myself.when i create them, i will auto call init() function to do what i want.
thanks!
