title: Gulp plugin for checking number of SCSS classes
body: <p>this is more of a general question/guidance thing.</p>
  
  <p>I'm using Gulp 3.x with a <code>gulpfile.js</code> along with <code>gulp-sass</code> &amp; <code>gulp-watch</code> and some other Gulp plugins. What I'm looking to do is to be able to scan all my SCSS files and pick out the number of classes etc and then setup a task whereby if the total number of classes drops below X (as an example, someone tries to remove large chunks of styling) it would then throw an error.</p>
  
  <p>Does anyone know of a package or what I need to look for to achieve this. I'm using NPM.</p>
