* This class is responsible for a lot of the heavy lifting around creating an animation at a certain state in time.
* The tricky thing is that when a new commit has to be "born," say in the middle of a rebase
* or something, it must animate out from the parent position to it's birth position.
* These two positions though may not be where the commit finally ends up. So we actually need to take a snapshot of the tree,
* store all those positions, take a snapshot of the tree after a layout refresh afterwards, and then animate between those two spots.
* and then essentially animate the entire tree too.
