Layer transparency

[Jennigma (Jennifer Leigh)]

Argh. This is the metaphor issue we were talking about here:

Multiple layers?

I agree that the wording doesn’t convey unambiguously. My metaphor for the keymaps is like a kids picture book with transparent overlay pages, but of course that fails because with a keymap stack you can apply each layer independently without the ones below it, while in a picture book if you are looking at layer 3 then layers 1 and 2 are also active. A metaphor of a stack of layers with toggle switches would more closely reflect the design than my picture book, so I see the merit of “Toggle.” …

I’ll adjust the intro document to be more correct right now. Might make sense to make a comment about this in the Model01-Firmware.ino as well. I am still not convinced that renaming the function names is the best course, but this behavior is going to confuse a lot of smart people, and we should think seriously about how to mitigate it.
