> AbstractFileInputOperator scans a directory for files and outputs the file 
> contents. However, when the directory is empty nothing is sent. A downstream 
> operator may want some basic information that the input directory is scanned, 
> so for example, it can create an output folder. Add a notification to the 
> operator when the directory is scanned for the first time. An implementation, 
> for example, can use this notification to send a control tuple with the 
> directory path notifying the downstream that the directory has been visited.
