What is the G7-specific Code?

[inventor96]

Piggy-backing on @tynbendad's comment at #3399 (reply in thread), I'm looking to help find all of the code that enables support for the G7 transmitter. Not being familiar with the xDrip+ codebase, the best I've been able to do so far is find all commits that mention "G7".

@Navid200 it looks like you were the author of every single one of them. 😉 If you're able to provide a summary or any insights, that would be awesome.

Of course anyone else is also welcome to contribute.

At any rate, this is the list of commits that I found, in chronological order:
