Front-end Boilerplate using Sass and Gulp 4 (php flavor)

Goals:

Save time by creating a boiler-plate for future project endeavors. 
Allow other devs to see how to gracefully migrate from Gulp 3 -> Gulp 4! 

*  Understand Gulp 4 rich features such as series. 
*  Understand basic layout of a gulp file 
*  How to automagically update the browser on new changes 
*  How to build Sass from CSS 
*  How to bundle/concate JS and CSS files and move them to a 'production location'
*  How to automagically include href of the bundled version in your code :) 

Quickstart:

1. Clone the repo 
2. Must have npm /node.js installed 
3. Also for php flavor - install the php (I'm running PHP 7.4.2)
