Class: Node

节点对象

核心属性：坐标(x,y)和尺寸(width, height)

创建一个节点, 有以下几种形式：

// 留意: 要先引入Node，因浏览器有一个同名的Node对象，忘记导入会出错
import {Node} from '@jtopo/core';

// 示例:
let node = new Node();
let node = new Node('name');

let node = new Node('name', x, y);
let node = new Node('name', 10, 10);

let node = new Node('name', x, y, width, height);
let node = new Node('name', 10, 10, 30, 30);

let node = new Node(null, x, y, width, height);

// 尺寸
node.resize(40, 40);

// 等价于
node.width = 40;
node.height = 40;

// 位置 (x、y代表了节点的中心在父节点的坐标)
node.setXY(100, 100);

// 和setXY完全等价，可看作是translate的简写
node.translate(100, 100);

// 单独设置x坐标
node.x = 100;
// 单独设置y坐标
node.y = 100;

// 也可以通过left、bottom、top、right设置节点位置(会根据宽度自动计算出x、y)
node.left = 0;
node.bottom = 0;
node.top = 0;
node.right = 0;
