Silverlight StoryboardManager 故事板管理类
写的不好，希望志同道合者给点建议，或者直接修改来完善它，当前版本暂定为V1.0
通过简单的设置ScaleDoubleAnimation、SkewDoubleAnimation、RotateDoubleAnimation、TranslateDoubleAnimation属性快速的实现放大缩小、倾斜、旋转、位移的动画效果
然后执行 storyboardManager.Storyboard.Begin();即可实现简单的动画效果，也可以同时给多个属性赋值，实现多种动画效果组合。
目前还不太灵活，希望大家帮忙改进，或提一些宝贵意见，谢谢
具体使用方法在下面

storyboardManager.Storyboard.Begin();
}
void MouseEnter( object sender, MouseEventArgs e)
{
StoryboardManager storyboardManager = new StoryboardManager(sender as FrameworkElement);
storyboardManager.ScaleDoubleAnimation.ScaleX = new DoubleAnimation() { To = 1.05 , Duration = TimeSpan.FromSeconds( 0.2 ) };
storyboardManager.ScaleDoubleAnimation.ScaleY = new DoubleAnimation() { To = 1.05 , Duration = TimeSpan.FromSeconds( 0.2 ) };
storyboardManager.SkewDoubleAnimation.AngleX = new DoubleAnimation() { To = 1.05 , Duration = TimeSpan.FromSeconds( 0.2 ) };
storyboardManager.SkewDoubleAnimation.AngleY = new DoubleAnimation() { To = 1.05 , Duration = TimeSpan.FromSeconds( 0.2 ) };
storyboardManager.RotateDoubleAnimation.Angle = new DoubleAnimation() { To = 360 , Duration = TimeSpan.FromSeconds( 0.2 ) };
storyboardManager.Storyboard.Begin();
