Performance timing plugin

This plugin gathers metrics regarding document navigation. For example, this interface can be used to determine how much time it took to load the page for a group of users/device types.

import {ceddl} from '@ceddl/ceddl-polyfill';
import {PerformanceTiming} from '@ceddl/ceddl-aditional-inputs/dist/performance-timing';

PerformanceTiming.run(ceddl);

ceddl.eventbus.on('performanceTiming', function (data) {
  console.log(data);
});
