Merge
Create 'constants' for rating and voting div id prefix in stead of hard coding it
Moved 'highchart' from Service to graphDirective.js as new function named 'createNewChart'. Removed title and labels
Added questions above vote and rate graphs
Replaced rgb color with hex for background color of graphs so it is identical with accordion body background
Fixed graphs so animation works by removing series each time new one is set
Fix the width of highcharts so they adapt responsively
Corrected size of smileys in graphs from 40 to 44 px
