EasingJS 0.1.0 README
=====================
Easing is a JavaScript port of Robert Penner's easing algorithms for
ActionScript (http://robertpenner.com/easing/).  The latest version of
this library is always available online at the following URL:

Using EasingJS
==============
You can use this library in an object-oriented (OOP) or procedural
manner.  Here's an object-oriented example:

    // create new quadratic easer
    var e = new Easing.Easer({
      type: 'quadratic',
      side: 'both'
    });

    // calculate ease at 50 out of 100 time units 
    // for a tween from 10 to 300 
    var x = e.ease(50, 10, 290, 100);

And here's the same result, using the procedural API:

    // calculate ease at 50 out of 100 time units 
    // for a tween from 10 to 300
    var x = Easing.quadratic.ease_both(50, 10, 290, 100);

A test page which allows you to try the various side and type
combinations is available in the test/ directory, or online at
the following URL:

EasingJS Modes
==============
Available easing types:

  * bounce:     Bounce easing.
  * circular:   Circular easing.
  * cubic:      Cubic (x^3) easing.
  * elastic:    Elastic easing.
  * exp:        Exponential (2^x) easing.
  * linear:     Linear easing (default).
  * quadratic:  Quadratic (x^2) easing.
  * quartic:    Quartic (x^4) easing
  * quintic:    Quintic (x^5) easing.
  * sine:       Sinusoidal (cos(x)) easing.

Available easing sides:

  * none:       Don't ease either side (default).
  * both:       Ease both sides.
  * in:         Ease in.
  * out:        Ease out.
