}

- (id)initWithCoder:(NSCoder *)decoder {
    if((self = [super init])) {
    //decode properties, other class vars
        NSDictionary* propertyDict = [Utils propertiesForClass:[self class]];
        for (NSString* key in propertyDict) {
            id value = [decoder decodeObjectForKey:key];
            [self setValue:value forKey:key];
