In BDFiddle, "Email Output" checkbox is working only for conversions and not for extractions. This task needs changes to made to Clowder and BDFiddle. Clowder needs to get username, check for status of extractors and when all extractors are done, it needs to send an email to the user. In BDFiddle, when extractors are chosen, a parameter needs to be added to the request for Clowder api endpoint to read.
