Review Comment:
   > If there is a copyright statement do not modify the file.
   
   As far as I can tell, every single source file in this project already has a copyright statement so
   
   > If there is no copyright statement there should be an Apache V2 text block. If it is not there insert it.
   
   Is never going to happen until we add new source files (which hasn't happened yet).
