     * Registers the runtime class information for a class.This method adds some strings which represent the class name or
     * some interface names to the class definition. After the registration,you can use egret.is() method to do the type checking
     * for the instance of this class.<br/>
     * Note:If you use the TypeScript programming language, the egret command line tool will automatically generate the registration code line.
     * You don't need to manually call this method.
     *
     * @example the following code shows how to register the runtime class information for the EventDispatcher class and do the type checking:
     * <pre>
     *      egret.registerClass(egret.EventDispatcher,"egret.EventDispatcher",["egret.IEventDispatcher"]);
     *      let dispatcher = new egret.EventDispatcher();
     *      egret.log(egret.is(dispatcher, "egret.IEventDispatcher"));  //true。
     *      egret.log(egret.is(dispatcher, "egret.EventDispatcher"));   //true。
     *      egret.log(egret.is(dispatcher, "egret.Bitmap"));   //false。
     * </pre>
     * @param classDefinition the class definition to be registered.
     * @param className  a unique identification string of the specific class
     * @param interfaceNames a list of unique identification string of the specific interfaces.
     * @version Egret 2.4
     * @platform Web,Native
     * @language en_US
     */
    /**
     * 为一个类定义注册运行时类信息,用此方法往类定义上注册它自身以及所有接口对应的字符串。
     * 在运行时，这个类的实例将可以使用 egret.is() 方法传入一个字符串来判断实例类型。
     * @example 以下代码演示了如何为EventDispatcher类注册运行时类信息并判断类型：
     * <pre>
     *      //为egret.EventDispatcher类注册运行时类信息，由于它实现了IEventDispatcher接口，这里应同时传入接口名对应的字符串。
     *      egret.registerClass(egret.EventDispatcher,"egret.EventDispatcher",["egret.IEventDispatcher"]);
     *      let dispatcher = new egret.EventDispatcher();
     *      egret.log(egret.is(dispatcher, "egret.IEventDispatcher"));  //true。
     *      egret.log(egret.is(dispatcher, "egret.EventDispatcher"));   //true。
     *      egret.log(egret.is(dispatcher, "egret.Bitmap"));   //false。
     * </pre>
     * 注意：若您使用 TypeScript 来编写程序，egret 命令行会自动帮您生成类信息注册代码行到最终的 Javascript 文件中。因此您不需要手动调用此方法。
     *
     * @param classDefinition 要注册的类定义。
     * @param className 要注册的类名。
     * @param interfaceNames 要注册的类所实现的接口名列表。
     * @version Egret 2.4

     * @language zh_CN
