adding tags for the repo

[Amomo]

Hello,

Adding tags for repo could specify points in history and mark release points. It's helpful for user to know the version and status of repository, and would enable wider distribution of the library, for example it could be hosted by cdnjs (website)

Would you please consider on using tags? Thanks for your great work!
