        id value = [self valueForKey:key];
        [encoder encodeObject:value forKey:key];
    
}

- (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];
        }
    }
    return self;
}
