How to check if cache is actually operational?

[FastNinja]

I need to verify that app actually using cache when it is supposed to use cache instead of downloading the file.

I am not sure how exactly do that?
Options:

• some kind of debugInfo might be helpful that can be switched on or off?
• Callback (crazy idea):

   image: new CachedNetworkImageProvider(imageUrl, 
              onImageProvided: (imageFile, fromCache) => 
                  { /*
                       here developers can do something with file, or log, or alternate for how long it 
 should stay etc...
                    */
                    } ),

but basically I want to see somewhere:

 loaded from from URL 'www.site.com/file.png',
 used file from cache 'www.site.com/file.png',
...
...
used file from cache 'www.site.com/file.png',

Yes options for loging would be a good idea. The callback is more work and kind of a breaking change. Do you see much use for that?

I guess I will add some debug logging with the option to turn it on or off.

logs are enough for sure!

For issue #8 I was already building some logging, so will add that in a next release.

Added in the Cache Manager so this will be added in the next release.
