/**
* @class Ext.fx.Easing
*
This class contains a series of function definitions used to modify values during an animation.
They describe how the intermediate values used during a transition will be calculated. It allows for a transition to change
speed over its duration. The following options are available:
- linear The default easing type
- backIn
- backOut
- bounceIn
- bounceOut
- ease
- easeIn
- easeOut
- easeInOut
- elasticIn
- elasticOut
- cubic-bezier(x1, y1, x2, y2)
Note that cubic-bezier will create a custom easing curve following the CSS3 transition-timing-function specification `{@link http://www.w3.org/TR/css3-transitions/#transition-timing-function_tag}`. The four values specify points P1 and P2 of the curve
as (x1, y1, x2, y2). All values must be in the range [0, 1] or the definition is invalid.

/**
* @class Ext.fx.Animator
* Animation instance
This class is used to run keyframe based animations, which follows the CSS3 based animation structure.
Keyframe animations differ from typical from/to animations in that they offer the ability to specify values
at various points throughout the animation.
__Using Keyframes__
The {@link #keyframes} option is the most important part of specifying an animation when using this
class. A key frame is a point in a particular animation. We represent this as a percentage of the
total animation duration. At each key frame, we can specify the target values at that time. Note that
you *must* specify the values at 0% and 100%, the start and ending values. There is also a {@link keyframe}
event that fires after each key frame is reached.
__Example Usage__
In the example below, we modify the values of the element at each fifth throughout the animation.
Ext.create('Ext.fx.Animator', {
target: Ext.getBody().createChild({
style: {
width: '100px',
height: '100px',
'background-color': 'red'
}
}),
duration: 10000, // 10 seconds
keyframes: {
0: {
opacity: 1,
backgroundColor: 'FF0000'
},
20: {
x: 30,
opacity: 0.5
},
40: {
x: 130,
backgroundColor: '0000FF'
},
60: {
y: 80,
opacity: 0.3
},
80: {
width: 200,
y: 200

100: {
opacity: 1,
backgroundColor: '00FF00'
