The only reason I used "fragment" was because both the RFC and 
the Wikipedia page called it that way. I hate to break protocol ;)

Now it allows you to create/edit an URI. You can do so by using 
an array or string, whichever you prefer.
I also added a toString() method and fixed the indentation to 4 
spaces, instead of 1 tab.

uri = new Uri();
uri.scheme = "foo";
uri.username = "username";
uri.password = "password";
uri.host = "example.com";
uri.port = 8042;
uri.path = ["over", "there", "index.dtb"];
uri.query = ["type": "animal", "name": "narwhal", "novalue": ""];
uri.fragment = "nose";
assert(uri.toString() == 
"foo://username:password@example.com:8042/over/there/index.dtb?novalue=&name=narwhal&type=animal#nose");
