 * Other standards and guidelines yet to be written down ;-)
 * These standards and guidelines should result in the posibility to create a complete new service by creating one module in one .h file allowing it to use all functionality available in StarBase. Including UI, pins, files, print, model persistent storage, enabling and disabling, loop injection etc. If you feel it's not possible, log a github issue.
