Advanced Markers Announced and in Preview

[onnij]

Hey Guys,

I recognize that this was literally just announced so I have no expectations on timeline or anything like that. But, I wanted to bring to everyone's attention in case there are some devs with more available time than me to take a gander, and potentially start making this usable with this package.

Looks to be a lot more extensible than the existing Markers system.
