/*
Some interesting special rules:
You can only transition from one animation to another at certain points.
The climb, mount, and dismount animations must be at their beginning or end
to transition.
If a climb or mount animation finishes and the key is not being held down, the idle
animation starts automatically.
If a climb or mount finishes and the key is being held down, the brain will *try*
to transition to the same stage, effectively looping it.
The idle can transition at any point.
The Release and FallOff aniamtions can forcibly transition *any* animation.
