// PLEASE NOTE: I have implemented a cache, but it currently never expires - so it won't pick up on deviations being renamed.
// Clear it manually by disabling the cache below:

var useCache = true;  // Set to true or false

// Define functions ################################################

// Flatten multiline data for the benefit of regexps
function flatten(x) {
	return x.replace(/[\r\n]/g, '');
}

// Set title to include deviation link and title
function setTitle(url, title) {
	var header = document.getElementsByTagName('h2')[0];
	header.innerHTML = header.innerHTML.replace(' Comment', ' Comment on <a href="'+url+'">'+title+'</a>');
