* General guidelines while writing helpers:
*
* - If returning HTML use return new Handlebars.SafeString();
* - If the helper needs optional arguments use the "hash arguments"
* Eg. {{{link . "See more..." story.url class="story"}}}
* NOTE: the first argument after the helper name should be . which will be context in the helper function
* Handlebars.registerHelper('link', function (context, text, url, options) {
* var attrs = [];
*
* for(var prop in options.hash) {
* attrs.push(prop + '="' + options.hash[prop] + '"');
* }
* return new Handlebars.SafeString("<a " + attrs.join(" ") + ">" + text + "</a>");
* });
*
*
* NOTE: Due to some limitations in the require-handlebars-plugin, we cannot have helper that takes zero arguments,
* for such helpers we have to pass a "." as first argument. [https://github.com/SlexAxton/require-handlebars-plugin/issues/72]
