Default documentation URLs for UIMA components

[reckart]

It would be great if one could configure default documentation URLs for readers/writers/engines at the POM level instead of having to add a @DocumentationResource in every component.

The value set in the POM should be used as a default. If an annotation is present in the component, it should be used instead.
