/**
* 复选框，可以单独或者在tm-groupcheckbox中使用。
* @property {Boolean} value = [true|false] 如果想双向绑定需要value.snyc等同v-model。推荐v-model.
* @property {Function} input 等同value.snyc和v-model和change
* @property {Function} change 变化是会返回 {index,checked,value:name携带的数据}
* @property {Boolean} disabled = [true|false] 默认false,禁用
* @property {String} color = [primary|blue] 默认primary,主题色名称。
* @property {String} border-color = [] 默认 '',边线主题色，默认同color可不填。
* @property {String} model = [normal|round] 默认normal, 内部：normal打勾，round:内部为圆点
* @property {String} icon = [icon-check] 默认icon-check,自定义选中时的图标。
* @property {String|Number} round = [2|rounded] 默认2, 圆角，rounded时即圆形。
* @property {String|Number} size = [] 默认32, 大小单位upx
* @property {String|Boolean} dense = [true|false] 默认false, 是否去除外间隙。
* @property {String} label = [] 默认"", 文右边显示的选项文字
* @property {String|Boolean} black = [true|false] 默认false, 暗黑模式
* @property {String|Boolean} inline = [true|false] 默认false, 是否内联模式
* @property {String | Array | Object | Number} name = [] 默认 "", 选中时携带的自定义数据，会通过change带回。
* @example <tm-checkbox v-model="checked" label="苹果"></tm-checkbox>
