    /* The Bucket class is a container for trinkets and treasures.
    
    Two points of interest in this class are the weight and value
    accessor methods that we use to implement the weight and value
    AppleScript properties.  These accessors implement read only
    properties and they return a calculated result reflecting the sum
    total of the weights of all of the trinkets and treasures
    contained in the bucket.
    
    We take care of most of the 'infrastructure' type operations
    needed for scripting in the Element class (the superclass of the
    Trinket class), so all we have to worry about here is storage management
    and providing accessors for the properties.*/
@interface Bucket : Element {
    NSMutableArray *theTrinkets;
    NSMutableArray *theTreasures;
}
 
    /* storage management */

- (void)dealloc;
 
 
 
    /* kvc Cocoa property for the 'weight' AppleScript property.  Note that rather
    than simply returning a value, this method calculates its result by
    summing the weights of all of the trinkets and treasures contained
    in the bucket.
    
    Also note, 'weight' is a declared as a read only property in our scripting
    definition file so we have only defined a read only Cocoa property.  */
@property (nonatomic, readonly) NSNumber *weight;
 
 
    /* kvc Cocoa property for the 'value' AppleScript property.  Here also rather
    than simply returning a value, this method calculates its result by
    summing the values of all of the treasures contained in the bucket.
    And, as with the 'weight' property, 'value' is a declared as a read
    only property in our scripting definition file so we have only defined 
    a read only Cocoa property. */

    /* kvc methods for the 'trinkets' AppleScript element.  Here we implement the methods

    In our scripting definition file we specified that the 'bucket' class contains an
    element of type 'trinket', like so:
        <element type="trinket"/>
    Cocoa will use the plural form of the class name, 'trinkets',  when naming the
    property used by AppleScript to access the list of buckets, and we should use
    the property name when naming our methods.  So, using the property name, we
    name our methods as follows:
        - (NSArray*) trinkets; (implied by property declaration)
        -(void) insertInTrinkets:(id) trinket;
        -(void) insertInTrinkets:(id) trinket atIndex:(unsigned)index;
        -(void) removeFromTrinketsAtIndex:(unsigned)index;
    */
 
    /* return the entire list of trinkets */
@property (nonatomic, readonly) NSArray *trinkets;
 
    /* insert a trinket at the beginning of the list */
-(void) insertInTrinkets:(id) trinket;
 
    /* insert a trinket at some position in the list */
-(void) insertInTrinkets:(id) trinket atIndex:(unsigned)index;
 
    /* remove a trinket from the list */
-(void) removeFromTrinketsAtIndex:(unsigned)index;
 
 
 
 
 
    /* kvc methods for the 'treasure' AppleScript element.  Here we implement the methods

    In our scripting definition file we specified that the 'bucket' class contains an

        <element type="treasure"/>
    Cocoa will use the plural form of the class name, 'treasures',  when naming the
    property used by AppleScript to access the list of buckets, and we should use
