// This determines if the object (CFTypeRef) is an instance of the class named in type. The type is usually the var type minus "Ref".
// For instance to determine if an NSString* is really an NSString*, APEObjectIsType(string, CFString).
// This works for all toll-free bridged types such as using APEObjectIsType(timer, CFRunLoopTimer) where timer is an NSTimer* instance.
// Special notes: NSBundle and CFBundleRef are not toll-free bridged. And as of 10.4, there is no HIObjectGetTypeID() yet so you cannot
// check to see if a specific object is an HIObjectRef until 10.5. If object is a Cocoa object, it must be toll-free bridged with a CF version.
