FutureBlobFile

This is an answer type Answer\<FutureBlobFile\> used by multimodal questions to store the localFilePath and the futureBlobId of a file. The local file will will be uploaded to the blob storage during the completion of the questionnaire. This is a temporary answer type, which is not stored in the database. It will be replaced by Answer\<String\>, in which the String is the futureBlobId.
