Subject: [PATCH] Label`s Lazy-Initial&Rewrite(setFrame:)

1. Use the lazy-Initial method to create the progressLabel
2. rewrite (setFrame:) method to make sure that the progressLabel also
could be created , when I use the method
[[DALabeledCircularProgressView alloc] init] , and set the frame later.
