Publicity chair tools

This Java app has been developed and used as part of the Publicity Chair role for the Vamos 2022 conference, https://vamos2022.isti.cnr.it/. The application connects through biblioproxy to download a series of publications, identified by their doi, and then processes the pdfs to extract the emails of authors. It is useful to create the list of participants of the last editions of specific conferences, useful for publicity chair purposes.
