implementation-notes.md

From the CRC:

• Does implementation-notes.md adequately describe the implementation, with an overview that will be useful to future maintainers?

See https://github.com/phetsims/geometric-optics/blob/master/doc/implementation-notes.md

I added to the implementation node before the code review although there is surely more confusing aspect of the similation that could be fleshed out.

Honestly. I thought that was a very intelligently written implementation notes markdown. It helped get me up to speed quite well on the physics and code structure. Up to you how much more you would like to flesh out.

I make another pass through this later, to note any changes that I make.

See #196 (comment) for terminology used in the code. This should be used to revise implementation-notes.md.

implementation-notes.md is ready for review by whoever does the sim code review.

@jonathanolson Please review as part of code review #402.

Implementation and model notes are excellent! Thank you.
