+/**	EXPLANATION:
+ * Components are API-exposing sub-components of an application. They are used
+ * aggregate the resources and API of some logically distinct sub-system into
+ * a single abstract entity. Basically, a component is a way to bind some APIs
+ * and resources to a particular thread. Ideally, all accesses to the resources
+ * of a component should be made through the component's APIs.
+ *
+ * Multiple components can share the same thread; and for this reason, each
+ * component must be supplied with a reference to the thread it shares.
+ * This amounts to saying that a single thread may expose and serve multiple
+ * APIs.
