project. Right now the usual mode works but the signal view mode used in the DBC editor is broken. Committing because the changes are so major they should be spread out into a few commits

/*
|
|
* CANDataGrid is a custom QT widget that proves that it's possible to shoehorn 12x too much crap into one widget. The purported
|
|
* goal of the widget was to show an 8x8 grid of bits that show whether each bit in a given message is set or not. It allows one to quickly
|
|
* visualize the bits within a CAN frame's data bytes. From there it evolved to also show whether a given bit was freshly set recently, freshly
|
|
* unset recently, or has stayed set or unset for a while. It can also gray out bytes that don't exist in the current CAN frame.
|
|
* This is handled by the calling code.
|
|
*
|
|
* After that functionality was added so it could also emit a signal when it is clicked. The signal will tell you which "bit" cell was clicked.
|
|
*
|
|
* Then, support was added for modifying the text color of each cell. This can be used for whatever the calling code wants. An example is
|
|
* FlowView that uses all of the above functionality plus this functionality in order to show which bits are set as triggers for stopping
|
|
* the flowview playback.
|
|
*
|
|
* Now the control also tracks which signal is using which bit. The graphical representation does exist now but some tweaking is probably
|
|
* still needed. Also, it seems like it is necessary to allow for a variety of modes.
|
|
*
|
|
* And now, CAN-FD added as the cherry on top! It's a mess but really, all this functionality is handy to have.
