 *
 * The HttpServer object is used to create a very basic HTTP Server, used mainly

 *            foo: "bar"
 *          }
 *      };
 *
 *      env.server = new this.HttpServer({
 *          port: 9991,
 *          uris: env.expected
 *      });
 *      this.assertAnd(env.server.run(), true);
 *
 * Parameters:
 *
 *   object conatining the properties:
 *       port - port to run on
 *
 *       uris - an object where the first set of properties are URIs the values
 *              attached to them are the data sets to return.
