The first thing to realize is that by importing "String" you are
overriding the String from Java.  That's ok, except that the method
arguments to main expect java.lang.String.

Secondly, it is necessary to have a call like:
  
   Globals.env.initSwarm ("test", "0.0", "address@hidden", args);
  
..as the first call in `main', or at least before any use of the Swarm
libraries.

Thirdly, it is necessary to pass Globals.env.globalZone (or some other
zone) as an argument to Swarm constructors, e.g.

   swarm.collections.String s = new StringImpl (Globals.env.globalZone);  

Note the use of "swarm.collections.String" to differentiate from
java.lang.String.  

Don't forget to add a "import swarm.Globals" in order to
get unqualified use of the Globals class.  Otherwise you'd use 
"swarm.Globals" instead of "Globals".  

Finally, to print the swarm.collections.StringImpl you have instantiated, you
can use "Globals.env.xprint (s)".
