Paralaxer

Introduction

A react component that will animate its nested children based on scroll position. Each child that will be animated will take an animation object containing either a to and from style object, or multiple steps from 0 - 100. The Paralaxer Wrapper takes 2 / 4 arguments start and end, which are absolute values related to the document. or tresholdStart and tresholdEnd which are relative to the Paralaxer wrappers distance from the top of the screen.
