aries.set(opt)
path: __dirname, // template find root path
includeId: function, // ex: (templateId, cb) => return fs.readFile(path.join(__dirname,templateId+'.html'), cb);
cacheTime:10000, // 编译缓存时间，单位：毫秒
aries.compileFile(filepath, ctx, cb)
filepath:"async_example.html" // template relate to root path
ctx: {} // template ctx object
cb: function // ex: (err, renderStr, isUseCache) => {}
aries.compile(templateStr, ctx, cb)
templateStr:"<%= ctx.xxxx %>" // template relate to root path
ctx: {} // template ctx object
