Animate annotations

[mikrobi]

Any cool idea about how to achieve an animation like this: http://leaflet.github.io/Leaflet.markercluster/example/marker-clustering-realworld.388.html

This type of animation is not yet possible with the current interfaces.

#10 contains a prototype of an implementation. This wasn't merged because it lacked unit tests and because I don't think associate objects are needed to implement this feature. Perhaps you can have a look and see if you can improve the implementation.

Closing this in favor of #10
