<?php 
/*
* The goal of the Beautine application is to provide an input field
* where the user can type the name of a YouTube guru and then have 
* application output which products this guru is using for her hair
* nails and skin. To accomplish this task, the application is making 
* a request to the YT API for a channel and it's videos, for any 
* videos that have products listed in the description box, we display
* those products by in the appropriate hair, nails , skin list on 
* beautine's site. Of course, we'd want the products to be those  
* that are part of the guru's routine, rather than just a product 
* she happens to be reviewing, either paid to review or just curious

* At the suggestion of HackerSchool, I laid out the build goals for
* working each of the time durations
* 1 HOUR - text only


* 1 DAY - text & YT user thumbnail

* 2 DAYS - text, YT user thumbnail & product image from google/amazon
video ID uS3-x_2IGHs
