是否支持模块的动态加载？如何实现
================

当前不支持动态加载设备侧的二进制包。可以使用动态import进行异步加载，以实现类似Class.forName()的反射效果。

示例如下，hap动态导入harlibrary，并调用静态成员函数staticAdd()、实例成员函数instanceAdd()和全局方法addHarlibrary()。

// harlibrary's src/main/ets/utils/Calc.ets
export class Calc {
  public static staticAdd(a:number, b:number):number {
    let c = a + b;
    console.log('DynamicImport I am harlibrary in staticAdd, %d + %d = %d', a, b, c);
    return c;
  }
  public instanceAdd(a:number, b:number):number {
    let c = a + b;
    console.log('DynamicImport I am harlibrary in instanceAdd, %d + %d = %d', a, b, c);
    return c;
  }
}
export function addHarlibrary(a:number, b:number):number {
  let c = a + b;
  console.log('DynamicImport I am harlibrary in addHarlibrary, %d + %d = %d', a, b, c);
  return c;
}

// harlibrary's Index.ets
export { Calc, addHarlibrary } from './src/main/ets/utils/Calc'
