2. Implemented CouchUser (_users) and CouchSecurity (_security) support. …

   CouchUser* user = [_server userWithName:@"Alice"];
   user.password = @"secret"; // will be hashed on the server
   // set some additional properties
   [user setValue:@"Alice" ofProperty:@"firstname"];
   [user setValue:@"Wonderland" ofProperty:@"lastname"];
   if ([[user save] wait]) NSLog(@"Saved: %@", user);
   
   CouchSecurity* security = [_db security];
   security.readerNames = [NSArray arrayWithObjects:@"bob", nil];
   security.adminRoles  = [NSArray arrayWithObjects:@"boss", nil];
   // add an admin user
   [security addObject:user.name forProperty:kSecurityAdminNamesKey];
   if ([security update]) NSLog(@"Saved: %@", security);

3. Implemented Embedded Model properties. …

   With this setup a Model property can be embedded instead of referenced by ID,
   making it easy to develop a nested model structure. The next logical step is
   to enable this for NSArray properties - allowing embedding and referencing of
   other CouchModel objects.
   
   If an existing Model is embedded, it keeps a referenceID to the original Model.
   
   There are various ways to control the embedding behaviour, using hook methods:
   
   + (id) embeddedModelForDocument:(CouchDocument *)document
                            parent:(CouchModel*)parent
                          property:(NSString *)property;
   
   - (BOOL) isEmbedableModelProperty: (NSString*)property;
   - (BOOL) isEmbedableIn: (CouchModel*)parent forProperty:(NSString*)property;
   - (void) didEmbedIn: (CouchModel*)parent forProperty:(NSString*)property;
   - (NSDictionary*) embeddedPropertiesToSave;
   
   Example of creating a new embedded model:
   
   Student* alice = [self createModelWithName: @"Alice" grade: 9];
   Student* buddy = [alice embedModelForProperty:@"buddy"];
   buddy.name = @"Bob";
   [alice save];
   if (alice.buddy.name == bob.name) NSLog(@"Buddies");
   
   Example of embedding an existing model:
   
   Student* alice = [self createModelWithName: @"Alice" grade: 9];
   Student* bob = [self createModelWithName: @"Bob" grade: 7];
   [alice embedModel:bob forProperty:@"buddy"];
   [alice save];
   if (alice.buddy.name == bob.name) {
     NSLog(@"Buddies - referenceID: %@", alice.buddy.referenceID);
   }
