Kata

I added random tests to this kata, please refer to me if something is broken. If everything is fine i think this kata is valid for approval.

I puts these code to the example test block and it works, why I got error when I submit?

var nodes = new Nodes(10); // why you did not use new?(in your description)
nodes.connect(0,1); 
nodes.connect(1,2);
describe("Solution", function(){
  it("should test for something", function(){
    Test.assertEquals(nodes.isConnected(0,2), true);
  });
});

Some more tests are neede (look at my solution !!) And a test example would be nice too

An example test case would be nice. There is a good example in the description, just copy that to the example tests. Could use some more tests for the submit including some random ones. What should it do about infinite loops? connect(1, 2); connect(2, 1); isConnected(1, 3); and other edge cases? The example shows 10 nodes being created and then it references node 0. Are the nodes zero based or does Node(10) mean the largest index is 10 (ie nodes 0->10)? Cool concept. Fun Kata. Thanks!
