Perch Codemirror editor plugin

I required a codemirror editor for HTML syntax highlighting and autocompletion in the backend. Thanks to this forum post from Ronan Doherty https://forum.grabaperch.com/forum/10-27-2015-issue-adding-codemirror-text-editor-to-perch I was able to successfully create a new stripped down version using latest codemirror. I have it commited to github if anyone needs it. https://github.com/shubhojyoti/perch_codemirror

Thanks again Ronan.
