+/**
+ * The Proxy API is a major part of the client-side functionality of the 
+ * CRISTAL API, which provides client-side proxy objects that represent the 
+ * Items and Agents on the server. It is the main entry point for many 
+ * components, such as Scripts and Job execution. An AgentProxy is returned on
+ * login, and should be used as the root for all user-based CRISTAL interactions. 
+ * 
+ * <p>The Proxy API provides the following functionality:
+ * 
+ * <ul>
+ * <li><b>Transparent storage integration</b> - Combines direct database access
+ * with remote calls to data retrieval methods on the Items. This allows client 
+ * processes to load Item data directly from databases whenever possible 
+ * without bothering the CRISTAL server. For example, the LDAP Lookup 
+ * implementation allows client processes to load Item Properties directly from 
+ * the LDAP server.</li>
+ * 
+ * <li><b>Data object browsing and loading</b> - The proxy objects allow client
+ * processes to browse through the storage cluster structure beneath the Item, 
+ * and access the objects directly without having to unmarshall their XML forms.
+ * All object types have their own get methods, so there's no need to construct
+ * their paths nor cast.</b>
+ *
+ * <li><b>Item object and directory change notification</b> - When a proxy
+ * object is created, it notifies the CRISTAL server that its Item is located
+ * on, and it notified of all additions, deletions and modifications of objects
+ * within that Item so it can remain up-to-date. Client applications may use 
+ * the {@link ProxyObserver} interface to be notified of changes, using 
+ * {@link MemberSubscription} instances to set up push subscriptions to cluster
+ * contents. It also provides a mechanism for subscribing to directory paths, 
+ * so that domain tree browsers can implement asynchronous loading and update
+ * themselves when the tree changes.</li>
+ * 
+ * <li><b>Job querying</b> - Job objects may be retrieved directly from an 
+ * ItemProxy, and may also be filtered by Activity name.</li>
+ * 
+ * <li><b>Job execution</b> - The {@link AgentProxy} provides the main 
+ * execution method for Jobs. This method performs outcome validation and 
+ * executes required CRISTAL Scripts in the client process before the execution 
+ * is requested on the server. Additional execution methods to call Predefined
+ * Steps are also available.
+ * 
+ * <li><b>Utility methods for resolution and marshalling</b> - The AgentProxy 
+ * provides utility methods for finding Items in the directory by name, path, 
+ * or system key, and gives access to the Castor XML marshalling system to 
+ * transform CRISTAL objects to XML and back again.</li>
+ * </ul>
+ * <p>The core object of the Proxy API is the ProxyManager, which is initialized 
+ * as a static member of the Gateway on initialization. This object can be used
+ * to create a Proxy object from a Path from the directory, and maintains a
+ * connection to the server called the Proxy Update Notification Channel, 
+ * through which it subscribes to Items it holds proxies for so it can be 
+ * informed of changes to Item data through {@link ProxyMessage} objects.
+ *
