Easing and tweening classes for scserver and sclang. Ported from the Cinder C++ framework - original equations by Robert Penner.
NOTE: All these expects an input 0-1 as first argument to .value. If you give it out-of-range values the behavior is undefined.
see EaseGallery helpfile for a graphical overview. see below for examples.
