	 * Calendar 日历
	 * @description 日历组件可以查看日期，选择任意范围内的日期，打点操作。常用场景如：酒店日期预订、火车机票选择购买日期、上下班打卡等
	 * @tutorial https://ext.dcloud.net.cn/plugin?name=uv-calendar
	 * @property {String} date 自定义当前时间，默认为今天
	 * @property {Boolean} lunar 显示农历
	 * @property {String} startDate 日期选择范围-开始日期
	 * @property {String} endDate 日期选择范围-结束日期
	 * @property {String} mode = [不传 | multiple | range ]  多个日期 | 选择日期范围 默认单日期
	 * @property {Boolean} insert = [true|false] 插入模式,默认为false
	 * 	@value true 弹窗模式
	 * 	@value false 插入模式
	 * @property {Boolean} clearDate = [true|false] 弹窗模式是否清空上次选择内容
	 * @property {Array} selected 打点，期待格式[{date: '2019-06-27', info: '签到', data: { custom: '自定义信息', name: '自定义消息头',xxx:xxx... }}]
	 * @property {String} cancelColor 取消按钮颜色
	 * @property {String} confirmColor  确认按钮颜色，默认#3c9cff
	 * @property {String} title 头部工具条中间的标题文字
	 * @property {String} color 主题色，默认#3c9cff
	 * @property {Number} round :insert="false"时的圆角
	 * @property {Boolean} closeOnClickOverlay 点击遮罩是否关闭
	 * @property {String} startText range为true时，第一个日期底部的提示文字
	 * @property {String} endText range为true时，最后一个日期底部的提示文字
	 * @property {String} readonly 是否为只读状态，只读状态下禁止选择日期，默认false
	 * 
	 * @event {Function} change 日期改变，`insert :ture` 时生效
	 * @event {Function} confirm 确认选择`insert :false` 时生效
	 * @event {Function} monthSwitch 切换月份时触发
	 * 
	 * @example <uv-calendar :insert="true":lunar="true" :start-date="'2019-3-2'":end-date="'2019-5-20'"@change="change" />
