/**
 * Provides utility functions for working with Anonymously logged-in users. <br />
 * Anonymous users have some unique characteristics:
 * <ul>
 *  <li>Anonymous users don't need a user name or password.</li>
 *  <ul>
 *    <li>Once logged out, an anonymous user cannot be recovered.</li>
 *  </ul>
 *  <li>signUp converts an anonymous user to a standard user with the given username and password.</li>
 *  <ul>
 *    <li>Data associated with the anonymous user is retained.</li>
 *  </ul>
 *  <li>logIn switches users without converting the anonymous user.</li>
 *  <ul>
 *    <li>Data associated with the anonymous user will be lost.</li>
 *  </ul>
 *  <li>Service logIn (e.g. Facebook, Twitter) will attempt to convert
 *  the anonymous user into a standard user by linking it to the service.</li>
 *  <ul>
 *    <li>If a user already exists that is linked to the service, it will instead switch to the existing user.</li>
 *  </ul>
 *  <li>Service linking (e.g. Facebook, Twitter) will convert the anonymous user
 *  into a standard user by linking it to the service.</li>
