Animation Control/Timeline

[mogmog]

This library is really impressive, especially on Mobile. As I am considering migrating my project over to this, one of the really useful things with Cesium is the ability to control the internal clock externally, so a camera path over time can be controlled by a slider component or similar.

As a feature request, would it be possible to expose setting the internal clock ticks or similar, to allow the same feature in this Library?
