Bug fix: would fail if a property was not present and the prototype is

version 1.1.4 - fix ES2015 module export

Fixed generated UMD distribution files (again)

Use prepublish instead of postinstall npm hook, since postinstall can only use direct dependencies and we need to use rollup to create
our UMD versions of traits.js.

fix mkdir throwing an error because npm already creates the dist folder

fix mkdirp not being usable when doing post-install

Version 1.1.0 - UMD version of traits.js

version 1.0.3 - unit tests now run in IE5-8 + code coverage data

version 1.0.2 - updates to README

version 1.0.1

Added ISC license, added continuous integration and fixed bower and npm
