public interface Annotator

This is an interface for adding annotations to a fully annotated Annotation. In some ways, it is just a glorified Function, except that it explicitly operates on Annotation objects. Annotators should be given to an AnnotationPipeline in order to make annotation pipelines (the whole motivation of this package), and therefore implementers of this interface should be designed to play well with other Annotators and in their javadocs they should explicitly state what annotations they are assuming already exist in the annotation (like parse, POS tag, etc), what field they are expecting them under (Annotation.WORDS_KEY, Annotation.PARSE_KEY, etc) and what annotations they will add (or modify) and the keys for them as well. If you would like to look at the code for a relatively simple Annotator, I recommend NERAnnotator. For a lot of code you could just add the implements directly, but I recommend wrapping instead because I believe that it will help to keep the pipeline code more manageable.
