/**
* An Appliance is the basic tool merlin wraps around a component to
* provide support for lifecycle and lifestyle management. Different
* implementations of Appliance can be plugged into the merlin system
* to allow merlin to manage a variety of components.
*
* The name appliance is used to call up an association with a kitchen
* utility like a microwave. Merlin acts as a chef in his kitchen, and uses
* various appliances to "cook up" various components as the restaurant
* customers (which can be other components or systems on the other end
* on the planet) ask for them.
*
* An appliance manages the establishment of a component
* type relative to a deployment criteria. Once established, an appliance
* provides support for the deployment of component instances on request.
* An appliance is responsible for component lifestyle and lifecycle
* management during the deployment and decommission cycles.
