Make clustering serializable?

[steemcb]

Hi great work on this project - I really like it. I was just wondering in order to avoid recalculating clusters each time the map is initialised could the clusters be serialized in some manner? I'm working on a app that has over 4K locations and the calculation of the initial clusters means it can take over 30 seconds for anything to appear on the map.

It seems like there might be a performance issue somewhere. In the sample app with 25K points distributed randomly across the planet, it only takes a few seconds for them to be randomly generated and clustered on the map on my Galaxy Nexus. Are you sure the delay is coming from Clusterkraf?
