    /**
      此类为GoJS模型数据对象实现检查器。
      构造函数采用三个参数:
        {string}分隔一个字符串,该字符串引用要检查的div的HTML ID。
        {Diagram}图是对GoJS图的引用。
        {Object} options可选的JS Object,描述检查器的选项。

      选项:
        inspectSelection {boolean}默认为true,是否自动显示和填充Inspector
                                   与当前选择的图零件。如果设置为false,则检查器将不显示任何内容
                                   直到您以Part或JavaScript对象作为参数调用Inspector.inspectObject(object)。
        includesOwnProperties {boolean}默认为true,是否列出当前在检查的数据对象上的所有属性。
        properties {Object}一个字符串对象:对象对,代表propertyName:propertyOptions。
                            可用于包括或排除其他属性。
        propertyModified函数(propertyName,newValue)回调
        multipleSelection {boolean}默认为false,是否允许多重选择并更改所有选定属性而不是
                                    单个第一个对象
        showAllProperties {boolean}默认为false,与multiSelection一起显示的属性在false时使用属性的相交还是在true时使用并集
                                    仅在multipleSelection为true时影响
        showSize {number}默认值0,显示选择多个节点时显示多少个节点
                          当其小于1时,显示所有节点

      属性选项:
        show:{boolean | function}一个布尔值,以向检查器显示或隐藏该属性,或者一个谓词函数以有条件地显示。
        readOnly:{boolean | function}该属性是否为只读
        类型:{string}描述数据类型的字符串。支持的值:“字符串|数字|布尔值|颜色|数字数组|点|矩形|大小|位置|边距|选择”
        defaultValue:{*}属性的默认值。默认为空字符串。
        选择:{Array | function}当type ==“ select”时,要使用的选择数组或返回选择数组的函数。

      Inspector的用法示例:

      var inspector = new Inspector("myInspector", myDiagram,
        {
          includesOwnProperties: false,
          properties: {
            "key": { show: Inspector.showIfPresent, readOnly: true },
            "comments": { show: Inspector.showIfNode  },
            "LinkComments": { show: Inspector.showIfLink },
            "chosen": { show: Inspector.showIfNode, type: "checkbox" },
            "state": { show: Inspector.showIfNode, type: "select", choices: ["Stopped", "Parked", "Moving"] }
          }
        });

      这是检查器在给定的DIV元素内创建的基本HTML结构:

      <div id="divid" class="inspector">
        <tr>
          <td>propertyName</td>
          <td><input value=propertyValue /></td>
        </tr>
