Odin CLI

Okay, I did a couple of things here. It may jsut be best to check the code out rather then look through the commits.

* The CLI is now based off [odin](https://github.comjwaldrip/odin).
* Reorganized of responsibility into tug sub packages.
* Removed `help` and `version` 
  * odin provides them by default as flags using `--help` and `--version`
