 * @property {Function} input value变化时触发.
 * @property {Number} value = [] 通过value来赋值进度,如果想双向绑定需要value.sync,建议使用v-model.
 * @property {Number} width = [] 宽度,默认自动宽度,单位rpx,也可输入百分比或者其它类型比如5px
 * @property {Number} height = [] 高度,默认6,单位upx,也可输入百分比或者其它类型比如5px
 * @property {String} shape = [round|square] 默认round,方形:square,半圆形:round.
 * @property {String} color = [] 默认primary,可以是16进制,rgb,rgba,主题色名称.
 * @property {String} bg-color = [] 默认 grey-lighten-4 ,背景颜色
 * @property {Boolean} loading = [true|false] 默认false,自动加载中...
 * @example <tm-propress v-model="checked"  ></tm-propress>
