Flash on drawRect: calls

To implement, call [[DCIntrospect sharedIntrospector] flashRect:inView:] inside the drawRect: method of any view you want to track.

When Flash on drawRect: is toggled on (binding: %@) the view will flash whenever drawRect: is called.

Naming objects & logging code

By providing names for objects using setName:forObject:accessedWithSelf:, that name will be shown in the status bar instead of the class of the view.

This is also used when logging view code (binding: %@). Logging view code prints formatted code to the console for properties that have been changed.

For example, if you resize/move a view using the nudge keys, logging the view code will print view.frame = CGRectMake(50.0 ..etc); to the console. If a name is provided then view is replaced by the name.
