Dynamic properties

Hi Josh (nice name!)

This ticket was at odds with #9 add OR support with category on NSObject? which moved ObjectiveResource from using a superclass, to implementing all the functionality as a category on NSObject. The downside of using a category is that there is no iVar support and, alas, Objective-C doesn't do "class" variables.

The only way that I now see to support this ticket would be to use a global or static map of objects to store all the attribute hashes, and I'm not to keen on that approach.

Do you have any other thoughts?

As a side note, the reason I wanted dynamic properties is because I almost always use iVar backed nonatomic,retain properties, which means that I need to repeat myself 4 times every time I want a new one.

@interface Foo {
  NSString *propertyName;
}
@property (nonatomic,retain) NSString *propertyName;
@end

@implementation Foo
@synthesize propertyName;
-(void) dealloc {
  [propertyName release];
  [super dealloc];
}
@end

Dynamic properties mean that I can cut that repetition down to 2, but my ideal solution would be not having to repeat anything. Does that mesh with what your logic?
