Description: ORegAnno's work queue allows registered users to input relevant papers from
scientific journals to a queue system for annotation. All that is required is a valid PubMED ID (PMID). Each added paper is set to PENDING. Any user can explicitly OPEN publications
from the queue that are PENDING, to begin the annotation process. Once a paper has been completely annotated, the user will set the publication state to CLOSED.
Otherwise, the user can revert the state back to PENDING. Comment fields are available for each change of state in the queue. A publication must be in the work queue
before it can be annotated. VALIDATORS can set the state of a CLOSED paper back to PENDING, if they feel something was missed, otherwise they may correct the annotation
