/*
This first order of business is to attempt to gain feature parity (roughly) with GVRET-PC so  that this
can replace it as a cross platform solution.

Here are things yet to do
- Ability to use programmatic frame sending interface (only I use it and it's complicated but helpful)

Things that were planned for the GVRET-PC project but never completed.
Single / Multi state - The goal is to find bits that change based on toggles or discrete state items (shifters, etc)
Range state - Find things that range like accelerator pedal inputs, road speed, tach, etc
fuzzy scope - Try to find potential places where a given value might be stored - offer guesses and the program tries to find candidates for you


Things currently broken or in need of attention:
1. Currently no screen supports dynamic updates when new frames come in.
2. Graph masks seem to not work - well, it does but it can turn into a 64 bit value and that doesn't work.
3. It's possible to close the main window and have the other open windows stay behind. That's weird.
4. There should be a way to write out the decoded messages/signals when a DBC file is loaded (new save format)
