INTERNALS.md somewhat confusing

[flexagontnt]

The current document appears difficult to understand (to me, at least). I think it would be easier and nice to format it using systems such as LaTeX or Mathquill. This could help aid newer individuals know how circuit simulators like this one works.

Note: I am not in any way attempting to offend the creator(s) of this project.

I recommend the book Electronic Circuit and System Simulation Methods by Pillage, et al, which explains all the math in better detail and better formatting.
