Adding cement dependency to setup.py
Removing generic data directory

Refacotring so that all scenario data is external to nepho in cloudlets
Basic cement controller stubs

Stubbing out cement controllers for the base nepho command and the three
built-in sub-commands, with initial help text.

Hadn't saved changes in Sublime Text!  Knew I should have sticked with

Adding core stubs and first function

Implemented "nepho cloudlet list" with pretty print. Added config
defaults and verified config file parsing.
minor color/error improvements to list function
Stubbing all cloudlet functions and fixing a typo
Adding argument for passing actual input
More work on scenario and stack controllers

Better listing/output, much-improved contextual help, better use of
argparse options, which involves breaking a bit out of how Cement wants
to force things.
