exposing API to allow users to create Custom Annotation

[ltiong]

Hello Alex,

I just wanted to post our conversation to share w/ the community:

Would it be possible to open up an API allowing the community to extend the base annotation class to create "custom" annotations?

Thanks,
Lu

Hello Lu,

Ok, we will add ability to create custom annotations in next version of library, I think in 2-3 weeks.

Best regards, Alexander
