Store parsed template in redis

[kayix]

When we parse template it returns javascript tokens. We can save these tokens in js file or in memory. I want to store them in redis database but they are not string. So is there any way to save them as string ? I already tried JSON.stringify but its not working.

As commented in #196 (comment), the tokens cannot be serialized currently. And I'm not sure whether it's worthwhile to deserialize instead of parse again. But I'll keep this issue open for more discussion.
