 Gets the current data that the manager is... managing.
 
 You can call this method as early as you want. The manager uses an operation queue to block 
 the completion block from firing until the data is downloaded. If the data is already downloaded, 
 then the queue is open and it executes right away.
 
 @param completion The completion block to fire. It takes one argument, the data that is returned,
 by the manager.
