Full end-to-end voting is working using the new binary encoding scheme, ballot combination and trustee partial decryption with tallies working perfectly. This required updating the Node server as well as Django models and views to support this. Emails to voters and trustees have also been updated to be more informative and look more professional. It could probably do at this point with using email templates and in the future HTML emails.
