/*
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
- Support saving frames
- Add flow view - ability to see bits change over time
- Implement the rest of the file loading formats
- Add frame counter to main screen and a way to auto scroll
- Ability to send frames via playback mechanism (people use this so get it working!)
- Ability to use programmatic frame sending interface (only I use it and it's complicated but helpful)
