v1.2.0

New Feature: dev viewer app that can be used to more easily compare/overwrite screenshots.

Launch with ./node_modules/.bin/chai-image-assert-viewer path/to/screenshot/dir.

Release 1.1.2

Bug fix: diff path should use same name as processed screenshot (so custom name should be respected if supplied).

Release 1.1.1

Bug fix: use AE metric (absolute error) instead of MAE (mean absolute error) to get number of pixels different, since return code of compare isn't completely indicative of difference.
