Implement utils/helpers to abstract common app patterns - Add helpers.confirm() to abstract the process of asking for confirmation. - Add helpers.selectDeviceType() to abstract the form needed to ask for device types. The functions on this module are reused by app actions. 2015-08-13 18:00:23 +00:00			`Promise = require('bluebird')`

Add `Aborted` error message when not accepting a confirmation This prevents a lot of duplicate code to check for confirmation status and exit from the current action. 2015-08-20 20:16:20 +00:00			`.then (confirmed) ->`
