LifecycleExtensionManager class. This class manages a list of extensions objects that are executed on components during the various stages of their lifecycles.

It provides methods for adding extension objects to the system, and a method for executing them on a particular component object. The current context is also passed in to the extension objects to facilitate the communication of any global values.

Extensions are stored internally in a list. This guarentees that the order in which they are executed matches the order in which they are inserted.
