Add ability to filter search results based on existing annotation

It would be very helpful to curators to have the option to filter search results based on existing annotation in, e.g. a GAF file.

Possible steps:

• Download annotation files

• Create a table with paper identifiers (e.g. PMID and/or doi) and type of annotation (e.g. C or F or P)

• Filter out papers from searches that match a record in the table (e.g. exclude papers that have already been curated for C)

• Users would have the option to filter all or a subset of papers according to the type of curation

It would also be helpful to be able to flag papers for exclusion from within TPC. In this use case, a record would be added to the table cited above.
