add com.fedorvlasov.lazylist, this helps to download the images in the
listview in async, moreover it will cache the images in the SD cards

The use of this library is to solve the problem of batch downloading
images in the list, because my previous asynchous image loading
implementation causes a problem that asyncTask rejects new Task when
many asyncTask are going on.

As you go into the app, search the artist, you will find a list of
artists with their names and their images
