Created HAPCharType and added vectors for required and optional characteristics to every service. Next up: add all HAP characteristic types to HAPCharType
Also moved StatusCode definitions from Settings.h to HAPConstants.h. There was no reason to have the user return a StatusCode of OK or UNABLE from update() since the only other choice was BUSY and HomeKit does not seem to distinguish errors. Either it's okay or not okay, which can more easily be represented by a simply return of TRUE or FALSE from update().
The user now needs to know nothing about StatusCodes. All Examples were modified to change StatusCode update() to boolean update() and return(StatusCode:OK) to return (true).
Much simpler.
This change allows the user to set the log-level with homeSpan.setLogLevel() instead of needing to change in Settings.h. Next up: Update Example that introduces VERBOSE to instead use setLogLevel(). Consider adding an interactive 'L' command to change this during run-time.
Also, added "#pragma once" to every *.h file to prevent duplication of definitions. TO DO: Review all #include to ensure sanity across all files.
