https://github.com/stanley-rozell/rtxi-settings
https://github.com/stanley-rozell/rtxi-stimLoader
https://github.com/stanley-rozell/rtxi-tdtSpikes
https://github.com/stanley-rozell/rtxi-tdtLFP
https://github.com/stanley-rozell/tdtUDP
https://github.com/stanley-rozell/rtxi-pldsSwitchedController

NOTE: will need to double check with MB before making these public

https://github.com/awillats/state-aware-control (satellite repo for manuscript and MATLAB analysis)
