grab bag of easing equations
npm install eases-jsnextThis is a fork of mattdesl/eases. It includes tree-shaking-friendly ES6 modules, and a UMD build for use in browser.
It preserves the original individual CommonJS files, and therefore serves as a drop-in replacement.

This is a grab-bag of Robert Penner's easing equations, most of the code from glsl-easings. Pull requests for optimizations are welcome.
``js
//require all eases
import * as eases from 'eases-jsnext';
//require only the single function
import { quadIn } from 'eases-jsnext';

All easing functions only remap a time value, and all have the same signature.
#### `v = ease(t)`
Where t` is typically a value between 0 and 1, and it returns a new float that has been eased.
