Description:

In the WebService section from the Installation and Administration Guide we
find errors when we execute the command to run the WebService.

After installing the service, we are told to run the service with "grunt
run" and that the expected output is the following:
 [2014-04-10 15:59:47.154] [INFO] console - Signaling server started
 [2014-04-10 15:59:47.157] [INFO] console - Express server listening on
port 3000 in development mode

However, when we execute the command the server is not started and we get
as ouput these lines:
$ grunt run
Running "shell:signaling" (shell) task

Done, without errors.

If we simply execute the command "grunt", we get a more explicit output:
$ grunt
Running "shell:signaling" (shell) task

Running "hub:watch" (hub) task
