Added classcoderpack

`classcoderpack` is a set of Javascript and CSS files to make a site look... good! The CSS (`theme-material.css` and `theme-basic.css` are themes and `classcoderpack.js` is to make dialogs disappear when their buttons are clicked)

Your structure in the original repo https://github.com/CodingWithClass/classcoderpack is /css/ and /js/ so the main file should probably be /css/theme-material.min.css
