手势的识别步骤：（自己写的继承MonoBehavior和KinectGestures.GestureListenerInterface接口的GestureListener脚本、KinectGestures
脚本、KinectManager脚本）
其中listener脚本要写，其他的赋给场景对象就行。
在listener脚本里的主要操作是实现KinectGestures.GestureListenerInterface接口里的一套流程函（都要public出来给KinectManager调用）
数：
void UserDetected(long userId, int userIndex){ } //玩家识别
void UserLost(long userId, int userIndex){ } //玩家丢失
void GestureInProgress(long userId, int userIndex, KinectGestures.Gestures gesture, float progress,
KinectInterop.JointType joint, Vector3 screenPos){ } //开始手势进度
bool GestureCompleted(long userId, int userIndex, KinectGestures.Gestures gesture,
KinectInterop.JointType joint, Vector3 screenPos){ } //手势完成
bool GestureCancelled(long userId, int userIndex, KinectGestures.Gestures gesture,
KinectInterop.JointType joint){ } //手势销除
在开始手势识别进度时，标志好要识别的手势；
在手势完成或销除时进行相应手势对比和操作；
另外，还要在Update函数里进行识别时间限定，识别时间超过2秒强制消除手势识别。
