feat(CompositionDecorator): added composition decorator

Browse Source 
It is sometimes useful for callers to be able to create new composition objects without overloading all the required methods. The CompositionDecorator acts as a simple translation layer which will pass any calls to virtual methods down to the next level of the composition stack (other than those which may have been overloaded by the caller)
