Possible implementation of annotateDocument()

* Change groupId - remove .stanford from end. 
* Depend upon non-SNAPSHOT concrete 1.1.2.
* Depend upon "fixed" version of concrete-agiga, 1.0.1-SNAPSHOT, which relies upon concrete 1.1.2.
* Fixed all compile errors. 
* Possible implementation of annotateDocument(). Needs testing/verification to ensure it's appropriate.
