1，修复一个因为疏忽造成的小BUG，编译之后的代码少 了一个{符号，呵呵
2，更改模板嵌套的编译模式，现在这种模式使用更简单方便，也更符合大家的习惯
3，增加了一个新的功能，其实本来提供的功能，也可以实现此功能，但是毕竟不专业，用起来不方便。此功能用来直接输出一个静态的文件，我曾经做过测试，这样直接输出，效率要比include高的多的多

此模板函数提供的标签及功能：
1，添加注释
{*   *}
2，输出变量
{$i}   //需要对变量进行格式化，可以使用{code()}标签来执行一个函数进行格式化输出
3，包含一个动态文件
{include()}
4，包含一个静态文件
{echofile()}
5，嵌套一个模板
{template()}
6，判断，分支
{if()} {elseif()}  {else} {/if}
7，循环
{while()}   {/while}
{foreach()}  {/foreach}
8，执行一段PHP代码，包括赋值，函数等等等等
{code()}
有了这些东西，基本上就没有什么工作完成不了了。
