以大学页面展示为内容，简单实现了大学页面展示包括动态展示大学图片、大学简介、用户评分、用户关注、用户登录
index控制器：/web/App/Home/Controller/IndexController.class.php
展示模板：/web/App/Home/View/Index/univpage.html
控制五星评分的js+css+php
js:/web/App/Home/View/Index/review.js
css:/web/App/Home/View/Index/review.css
用户关注写入数据库的原生php脚本（js ajax如何调用thinkphp方法还未明了）
/web/App/Home/View/Index/review.php
控制用户登录对话框弹出的js+css
js
/web/App/Home/View/Index/login_box.js
css:
/web/App/Home/View/Index/login_box.css
用户点击关注js+php
js /web/App/Home/View/Index/interest.js
用户关注操作写入数据库php
/web/App/Home/View/Index/interest.php
index控制器：/web/App/Home/Controller/IndexController.class.php
<pre name="code" class="php"><?php
/*
* 该部分主要作用是生成大学页面，展示大学信息以及用户评分 关注 留言公共展示，主要： 1.根据url输入参数动态生成大学信息，包括大学图片以及简介等，并将变量输出到对应html模板 2.网站入口页面(首页)index.html关联
