Parses command line arguments for issue #13
Captures the SSH server option
Passing the server address to the dispatched functions.
Added support in CircusClient for accepting a server address.  Existing functionality is unbroken but the client-side of the SSH connection has not yet been verified - need to implement SSH server first.

Correctly captures the server's address and completes SSH tunneling.
