Add a blog post to the README
Update es6-module-transpiler dependency
Update tests with new syntax
Version bump
feat(windows compatibility): correct paths in Windows

A couple of changes:
- replace backslashes from native format paths before using them in AMD require/define situations
- normalize linefeeds and file paths in tests
Version bump to v0.4.1
The `rjs` option is now named `amd`
Fix mixed CoffeeScript and JavaScript configs.
