--------------------------------------------------------------
Hmmm, in UIMA v3, I think the only actual supported implementations of
Annotation Feature Structures are instances of TOP.
So, I'm thinking we could add a method that takes AnnotationFS arg, and casts
it to TOP... ?
Tried that, got an ambiguous error when calling startAt(Annotation) because
Annotation has both supertype TOP and AnnotationFS.
Fixed that by adding a 3rd method: startAt(Annotation). So now have
startAt(TOP), startAt(AnnotationFS), and startAt(Annotation), the latter 2
casting their args to TOP.
Does this seem reasonable?

> Issue Type: Improvement
> Components: UIMA
> Affects Versions: 3.1.1SDK
> Reporter: Richard Eckart de Castilho
> Priority: Major
>
> The method
> SelectFSs<T> startAt(TOP fs);
> Does not accept an `AnnotationFS` instance as argument because AnnotationFS
> does not extend TOP. However, the documentation clearly states that this
> method requires an AnnotationIndex and a "starting position", so I guess it
> only works for subtypes of AnnotationFS?
