SteamUser user = connector.getUser();
user.getAttribute( SteamObject.USER_FIRSTNAME );
user.getAttribute( SteamObject.USER_LASTNAME );
// returns "0" which means it is "null" e.g. not set
user.getAttribute( "MYOWNKEY" );

user.setAttribute( "MYOWNKEY", "This is a test");

// returns "This is a test" now"
user.getAttribute( "MYOWNKEY" );

user.setAttribute( "MYOWNKEY", new Integer(12345) );

// returns 12345 as Integer now
user.getAttribute( "MYOWNKEY" );
