A minimal overhead event loop delay sampler.
npm install event-loop-delayA minimal overhead event loop delay sampler.
``

` js
const loopDelay = require('event-loop-delay')
const sampler = loopDelay()
setInterval(function () {
console.log('Accumulated delay in ms is', sampler.delay)
console.log('Accumulated times a delay was detected', sampler.times)

Running the above should run the sampler measuring the event loop delay.
#### sampler = loopDelay()
Make a new sampler. Will sample the event loop every 10ms.
#### sampler.delay
Accumulated event loop delay in ms measured since sampler was created.
#### sampler.times
Accumulated times the event loop delay was detected.
#### sampler.destroy()`
Destroys the sampler.
