notesutils

I should write this stuff up, but I haven't. I do have some brief notes on the "Notes.app" format here: https://github.com/dunhamsteve/notesutils/blob/master/notes.... But I didn't discuss my methodology -- Generic decoding of protobuf, building up a schema as you go -- the tricky part there is that a byte array and a substructure look the same, so you have to try to decode it, and if successful, try that schema on the next example. Here is another fun technique - scanning through a disassembly of an Apple framework looking for assembly patterns that match the protobuf compiler output (this was dependent on which language was targeted by protobuf): https://gist.github.com/dunhamsteve/224e26a7f56689c33cea4f0f... So you find the serializer / deserializer code and figure out what the original protbuf spec looked like.
