ThirdPersonCamera example has pedagogic issues

[ixxie]

The ThirdPersonCamera example is good, but suffers from several issues:

• [ ] Commented out code is in the example can confuse learners
• [ ] Components are imported from outside the example folder, making them hidden in the docs page (e.g. <Door>)
• [ ] Some of the files are quite large, and should ideally be split or simplified for pedagogic purposes

Thanks for the ping but I was under the impression this was something you'd like to tackle. I was of the opinion to remove this example in favour of a simplier implementation

I just pinged you so you can stay in the loop, nothing is expected otherwise.

A simplification is also a possible resolution here; I'm going to consider it when working on it.
