First Phase Release

This is the release for the first phase.
Some of the current features of the app:

• The app relies on a Firebase server.
• Firebase Authentication is used to authenticate users. New users can create a new account using an email or a Google account.
• Event and User object are stored on the Firestore database.
• Pictures for users or events are stored on Firebase Storage. After a picture has been uploaded on Firebase Storage, thumbnails of different sizes are generated using Firebase Cloud Functions and stored on Storage.
• The user (with the role manager) can edit and store his/her own event. An event is described by: a text, a category (friend party, concert, etc.), date, time, photo and address (with GPS coordinates).
• The GPS coordinates are generated from the address in a service.
• Photos are uploaded using a service, this is so that the upload continues even if the app is closed.
