I'm working on a project where we use TS and would like to add the CustomEase lib.    We have added the GSAP through NPM and since CustomEase isn't part of it for some reason I have hard time to find a way to get it working.    The error i recive is: !!! ERROR: browserify: Cannot find module '../TweenLite.js' from '/Users/myuser/Projects/myproject/src/ts'
