Project update week 10

We have solved some bugs and added some new features to the app. We now send location to the server whenever you start the app and whenever you chose to update. Receive a list of nearby users sorted by proximity. You can now follow a user and keep listening to his/her songs after the first song is finished. Shake the phone to start a song from a random nearby user feature is implemented. Best friend feature is added.

We are now working on fixing the user interface, implementing the NFC feature and implementing the point phone to get user feature.
