Add guide for how to move psuedo body through colliders with teleporter

**Update**

This is now simpler:

* add teleporter
* then you call the teleporter to move the play area
* Then in Teleported event call PsuedoBody.SnapToSource

------

Its not possible to simply teleport or move the play area through a collider with the pseudo body because it will resolve the collisions back to the rigidbody collider which cannot pass through colliders.

A simple guide showing how to achieve this with the teleporter:

* add teleporter
* then you call the teleporter to move the play area
* in Teleporting event, disable the PsuedoBody GameObject (to prevent divergence resolution)
* Then in Teleported event call Begin on a WaitForEndOfFrameYieldEmitter
* Then in the WaitForEndOfFraimeYieldEmitter.Yieleded event, just re-enable the PsuedoBody GameObejct (and allow it to re-sync)

Start with the updated procedure in this issue and inspect the Unity Teleporter and PsuedoBody events it names: Teleporting, Teleported, SnapToSource, and WaitForEndOfFrameYieldEmitter. Document how to add and call the teleporter, handle the relevant events, and re-enable the PsuedoBody after the end-of-frame wait; done means a newcomer can follow the guide to move the play area through colliders without divergence.
