## bugfix
- ajouter hello et nat a l'exp backoff OK
- peers n'ayant pas d'adresse OK
- verifier le refresh des peers
- setting in gui to act as a relay
- make hello and helloreply messages set the first extension bit to announce that peer is available for nat traversal
- implement actual nat traversal requests
- implement nat traversal :
- if hello/helloreply doesnt work with a peer, find a peer that supports nat traversal (server in priority) then begin protocol
## fonctionnalités :
- proposer des fichiers
- telechargement des fichiers
- receivers threads
- ask for nat traversal
rechercher les fichiers d'un pair

choisir un dossier à partager
