accurate-timer v0.0.9

An accurate, multienvironment timer

accurate_timer uses requestAnimationFrame() and performance.now(), defaulting to setInterval if it's used in a non-browser or older environment.

Based on my own (unscientific) measurements, the timer in a node.js environment tends to be accurate to about 3/1000ths of a second. In a browser environment it's a little less than 1/1000ths of a second.

Usage

• Create a timer object:

  	```js
  	var timer = new Timer(<callback>, <interval>);
  	```
  
  	The callback will be called every `interval` milliseconds.

• start / stop the timer:

  	```js
  	timer.start();
  	timer.stop();
  	```

All done! I hope you enjoy :blush:
