 * The main annotation of live data - reference to dynamic state variable

 * The advantage of Live Data is that there is no need to copy data into tsOutputChannels structure - Live Data is reading exactly
 * the same data as actual runtime logic. It's also important to have annotations of the View as close to actual implementation as possible
 * to increase the changes of those being in sync.
 *
 * One day Live Data could be replace with a Domain Specific Language
 * One day all Live Data could be provided to TS without data copy to tsOutputChannels - the idea is to have a virtual tsOutputChannels
 * where rusEfi would pull data from different memory ranges depending on the requested offset, more or less virtual pages. This could depend
 * on the TS bugfix described in https://github.com/rusefi/rusefi/issues/794?
