Filter dataset datatable on annotations
usecase : want to operate on (delete) a set of datafiles based on annotation values (they all have same filename)
add small form on page in which you could specify key/value to filter the datatable on (submit = JS hook for datatable ajax call)
other option is to add annotations in hidden col in datatable but would still need to verify by clicking datafile details (whereas a search func would be sure to return exactly what we want to match)
