Time Slider

[Maartenvm]

• Implement time slider from #4

A time slider with which one can search for things within a certain period is implemented on the Hadrianus website http://hadrianus.it/
Maybe a nice addition to that slider would be to also color the pins on the map according to their time, with a colorbar next to the map.

Or maybe something similar to this building history map of the Netherlands: http://code.waag.org/buildings/

That map is awesome!
