 * @english
 * This library uses ES2015 class system.
 * Class is the root class of class hierachy.
 * It provides utility methods to make it easier to manage configration options, merge mixins and add init hooks.
 *
 * @example
 * const defaultOptions = {
 *     'foo' : 'bar'
 * };
 * class Foo extends maptalks.Class {
 *     constructor(id, options) {
 *         super(options);

 *
 *     setId(id) {
 *         this.id = id;
 *     }
 *
 *     whenCreated() {
 *         // .....
 *     }
 * }
 *
 * Foo.mergeOptions(defaultOptions);
 *
 * Foo.addInitHook('whenCreated');
