**Version 4.1**  
 - DropboxBrowser now handles authentication and login with Dropbox. There is no need to check if the user is logged in to Dropbox before presenting the DropboxBrowser. If the user is not logged in, DropboxBrowser will prompt the user to do so. If the user opts-out of login then DropboxBrowser will dismiss itself. However, you may still handle login operations yourself.  
 - Updated delegate names  
 - Added code comments and standardized header definitions
