Would've added in getting as well, but the API kept 404'ing on me for that.
Note - Requires modification to nodester-api; see: nodester/nodester-api#9
Just noticed the API docs got fixed; adding in GET support!
Added in env get, env set, and env delete.
Merge pull request #35 from mintplant/master
Added in environment variable setting and deleting.
new npm modules published and working well! Nice job!
