1.2 Note Whether to change the default properties of the Smarty object 　　　　　　　

The default delimiter for the Smarty is {}, which can be modified in fact! How to modify?
You can modify the two properties of the Smarty:
Left_delimiter: Left delimiter, default = {
Right_dilimiter: Right delimiter, default =}

1.3 If you need to change the name of the default directory

　In Smarty, the name of the core directory cannot be changed casually! For example, the name of the template directory defaults to templates,

But can also be modified!

In smarty2.0, you can make changes with the following four properties:
Template_dir: Template directory, default is for templates
Compile_dir: Compile directory, default is Templates_c
Config_dir: Configuration directory, default to Configs
Cache_dir: Cache directory, defaults to cache
