/**
 * pagination.js 1.5.1
 * a jquery plugin to provide simple yet fully customisable pagination.
 * @version 1.5.1
 * @author mss
 * @url https://github.com/maxiaoxiang/jquery-plugins
 *
 * @调用方法
 * $(selector).pagination(option, callback);
 * -此处callback是初始化调用，option里的callback是点击页码后调用
 * 
 * -- example --
 * $(selector).pagination({
 *     ... // 配置参数
 *     callback: function(api) {
 *         console.log('点击页码调用该回调'); //切换页码时执行一次回调
 *     }
 * }, function(){
 *     console.log('初始化'); //插件初始化时调用该方法，比如请求第一次接口来初始化分页配置
 * });
