特性
可设定私有缓存或公共缓存，提高效率
可自由选择使用 Stream 组件或 FSO 组件
支持自定义文件编码
可保存文件
属性
Name
文本，该模板名称，主要用于使用公共缓存时区分不同模板。
Format
文本，文件编码类型，可设置值。
Object
文本，使用组件，可设置值：
Stream
FSO
PublicCache
布尔值，使用公共缓存，开启时模板文件将保存到Application对象，其他引用此模板类的对象设置相同Name值并同样打开公共缓存即可从缓存读取。（Load方法）
PrivateCache
布尔值，使用私有缓存，开启时模板文件将保存到对象内部变量，同一引用此模板类的对象可读取。（Load方法）
Direction
文本，模板文件所在目录，前后无需斜杠或反斜杠，如：template/default
File
文本，模板文件名，前边无需斜杠或反斜杠，如：default.html
SaveDirection
文本，保存文件所在目录，前后无需斜杠或反斜杠，如：html/default
SaveFile
文本，保存文件名，前边无需斜杠或反斜杠，如：default.html
对象
Code
文本，当前文本，使用SetVar方法时对此对象进行替换，使用Load方法时将模板重载到此对象
Storage
文本，已保存文本，使用SaveFront或SaveLast方法时将Code对象中文本保存到此对象的开头或结尾，可用于循环后得到所有代码
方法
ClearCache
清除公共缓存和私有缓存（强制从文件重载模板）
ClearPublicCache
清除公共缓存
ClearPrivateCache
清除私有缓存
ClearCode
清除Code对象
ClearStorage
清除Storage对象
SaveFront
将当前Code对象中文本保存到Storage对象开头
SaveLast
将当前Code对象中文本保存到Storage对象结尾
SaveCode
将当前Code对象中文本保存到文件
SaveStorage
将当前Storage对象中文本保存到文件
SetVar
对当前Code对象中文本进行替换
参数：需要被替换的文本，欲替换后的文本
Load
将模板文件载入Code对象，当开启并存在私有缓存时，从私有缓存载入，当开启并存在公共缓存时，从公共缓存载入，若无缓存则从文件载入
内部变量
ccStrPath
默认根目录
ccStrCookieName
默认Application对象名前缀
