/**
* Interface for convenience classes that wrap a {@link Context} to provide
* one-line access to a suite of {@link Service}s.
* <p>
* The {@link #get} methods provide consistent {@link Service} instantiation,
* while throwing {@link NoSuchServiceException} if the requested
* {@link Service} is not found.
* </p>
* <h3>Sample implementation</h3>
* <p>
* Let's say we have a {@code Kraken} service and a {@code Cow} service. Using
* the {@code Context} directly, the code would look like:
* </p>
* <pre>
* Context context = new Context();
* context.getService(Cow.class).feedToKraken();
* context.getService(Kraken.class).burp();</pre>
* <p>
* To perform these actions, you have to know <em>a priori</em> to ask for a
* {@code Cow} and a {@code Kraken}; i.e., your IDE's code completion will not
* give you a hint. Further, if either service is unavailable, a
* {@link NullPointerException} is thrown.
* </p>
* <p>
* But if we create a {@code Gateway} class called {@code Animals} with the
* following signatures:
* </p>
* <pre>
* public Cow cow() { return get(Cow.class); }
* public Kraken kraken() { return get(Kraken.class); }</pre>
* <p>
* We can now access our services through the new {@code Animals} gateway:
* </p>
* <pre>
* Animals animals = new Animals();
* animals.cow().feedToKraken();
* animals.kraken().burp();</pre>
* <p>
* This provides succinct yet explicit access to the {@code Cow} and
* {@code Kraken} services; it is a simple two-layer access to functionality,
* which an IDE can auto-complete. And if one of the services is not available,
* a {@link NoSuchServiceException} is thrown, which facilitates appropriate
* (but optional) handling of missing services.
* </p>
* <p>
* Gateways discoverable at runtime must implement this interface and be
* annotated with @{@link Gateway} with attribute {@link Plugin#type()} =
* {@link Gateway}.class. While it possible to create a gateway merely by
* implementing this interface, it is encouraged to instead extend
* {@link AbstractGateway}, for convenience.
* </p>
