JS easing and Expr easing

I ported the easing function made by Gregory Taylor from Gen to js and expr to be able to use them outside the audio world.
Quite useful to augment the line capabilies and/or map parameters usin sin, logarithmic, exponential, and many other.
Input and output are between 0. and 1. to make it easier to use. (Help file is provided).


PS : (Audio versions made by Gregory Taylor are available here : https://cycling74.com/forums/topic/easing-and-tweening-how-to-make-a-tulip/)

EDIT February 2017 : Now that Cycling’74 has incorporated easing in the package “ease”, this is deprecated, unless you don’t have access to the package manager.
