st2sdk doesn't parse top level option

Hi,

When I execute following command,

$ st2sdk -h

an exception is occurred.

vagrant@ubuntu2:~$ st2sdk -h

vagrant@ubuntu2:~$ 

Here is my environment.

vagrant@ubuntu2:~$ python --version
Python 2.7.6
vagrant@ubuntu2:~$ pip show st2sdk

Thank you.

Sorry, it seems to the problem of the cmd2 package.

And the usage is written in README, so this problem may be trivial.

Thanks for the report - will look into it as soon as I get a chance :)
