blockstack authentication

authentication.js

    /*
    Every app that uses multi-player storage must add itself to the user's profile.json file.
    The Blockstack Browser will handle this part automatically when the publish_data scope is requested during authentication.

    to read a another user file, you just need to call getFile with the appropriate options:
    const options = { username: username, decrypt: false, zoneFileLookupURL: 'https://core.blockstack.org/v1/names/'}
    getFile(statusFileName, options)

    }
    signOut() {
        blockstack.signUserOut(window.location.origin);
        console.log('sign out');
