"Yet another beautifier" for elixir eex/leex html templates. Like others it utilizes htmlbeautifier. The
diffrence is, it can format without saving the file first.
htmlbeautifier needs language settings to be set in the environment to handle utf-8 charsets - like umlauts.
On Macs the LC_* environment variables are not set by default. This extension will set them to en_US.UTF-8
if not set.
Formats eex / leex files without saving or producing tmp files.
