// 构建原型,添加原型方法或属性??
// 暂时用Object.create实现??

* 格式化文件大?? 输出成带单位的字符串
* @method formatSize
* @grammar Base.formatSize( size ) =& String
* @grammar Base.formatSize( size, pointLength ) =& String
* @grammar Base.formatSize( size, pointLength, units ) =& String
* @param {Number} size 文件大小
* @param {Number} [pointLength=2] 精确到的小数点数??
* @param {Array} [units=[ 'B', 'K', 'M', 'G', 'TB' ]] 单位数组。从字节,到千字节,一直往上指定。如果单位数组里面只指定了到了K(千字??,同时文件大小大于M, 此方法的输出将还是显示成多少K.
* @example
* console.log( Base.formatSize( 100 ) );
// =& 100B
* console.log( Base.formatSize( 1024 ) );
// =& 1.00K
* console.log( Base.formatSize( 1024, 0 ) );

* 如果`callback`中,某一个方法`return false`了,则后续的其他`callback`都不会被执行到??
* 切会影响到`trigger`方法的返回值,为`false`??
* `on`还可以用来添加一个特殊事件`all`, 这样所有的事件触发都会响应到。同时此类`callback`中的arguments有一个不同处??
* 就是第一个参数为`type`,记录当前是什么事件在触发。此类`callback`的优先级比脚低,会再正常`callback`执行完后触发??
