public interface Messager
Messager provides the way for an annotation processor to
 report error messages, warnings, and other notices.  Elements,
 annotations, and annotation values can be passed to provide a
 location hint for the message.  However, such location hints may be
 unavailable or only approximate.
 Printing a message with an error kind will raise an error.
Note that the messages "printed" by methods in this
 interface may or may not appear as textual output to a location
 like System.out or System.err.  Implementations may
 choose to present this information in a different fashion, such as
 messages in a window.
