this all loooks good, just had one comment on the saving with json exclude. Also, what exactly do we need this saving feature for? it seems as though we should be changing our json in json not in code (as that wwould be overwriting every time we set it and ask to save it)

@linglejack06 if we are able to save JSON based on log tunable number, then all we would need to do is figure out a way to sync the constants back from the robot to the driverstation

I'm thinking of the following process:

1. We are in test mode tuning stuff
2. We find a configuration for certain constants we want to save
3. We save the constants to JSON (no redeploy needed when restarting the robot)
4. Somehow we get the constants sent back to the driverstation repo (TBD how this works, maybe just FTP)
5. We check in the changes to the JSON files and push them to the repo

@avidraccoon this looks good, please fix the merge conflicts so we can do a final pass review
