	 * poup弹出层
	 * @description  poup弹出层，上下，左右方向。
	 * @property {Boolean} value = [true|false] 使用时value.sync可同步，也可不同步。等同于v-model
	 * @property {Boolea} v-model 显示和关闭。
	 * @property {String} position = [bottom|top|left|right|center] 方向可选bottom,left,right,top,center
	 * @property {Function} change 改变时会调用此函数，参数e等同于v-model和value
	 * @property {String|Number} width 宽，位置为left,right是起作用。可以是30%或者数字(单位upx)
	 * @property {String|Number} height 宽，位置为top,bottom是起作用。可以是30%或者数字(单位upx)
	 * @property {String|Number} round 圆角0-25
	 * @property {String|Boolean} black = [true|false] 暗黑模式
	 * @property {Boolean} over-close = [true|false] 是否点击遮罩关闭。
	 * @property {Boolean} is-filter = [true|false] 是否背景模糊
	 * @property {String} clss-style = [] 自定内容的类
	 * @property {String} bg-color = [white|blue] 默认：white,白色背景；请填写背景的主题色名称。
	 * @property {String} over-color = [] 默认：rgba(0,0,0,0.3), 遮罩层颜色值不是主题。
	 * @example <tm-poup height="85%"  v-model="show"></tm-poup>
