/**
* checkbox 复选框
* @description 复选框组件一般用于需要多个选择的场景,该组件功能完整,使用方便
* @tutorial https://uview-plus.jiangruyi.com/components/checkbox.html
* @property {String | Number | Boolean} name checkbox组件的标示符
* @property {String} shape 形状square为方形circle为圆型
* @property {String | Number} size 整体的大小
* @property {Boolean} checked 是否默认选中
* @property {String | Boolean} disabled 是否禁用
* @property {String} activeColor 选中状态下的颜色如设置此值将会覆盖parent的activeColor值
* @property {String} inactiveColor 未选中的颜色
* @property {String | Number} iconSize 图标的大小单位px
* @property {String} iconColor 图标颜色
* @property {String | Number} label label提示文字因为nvue下直接slot进来的文字由于特殊的结构无法修改样式
* @property {String} labelColor label的颜色
* @property {String | Number} labelSize label的字体大小px单位
* @property {String | Boolean} labelDisabled 是否禁止点击提示语选中复选框
* @property {Object} customStyle 定义需要用到的外部样式
*
* @event {Function} change 任一个checkbox状态发生变化时触发回调为一个对象
* @example <u-checkbox v-model="checked" :disabled="false">天涯</u-checkbox>
