 WIP:
  - turn Arduino's ino file into a set of cpp and header files
  - create separate class instances for heater, sensors, etc...
- - sepparate activities into independent tasks and RTOS threads
+ - decomposite project into independent tasks and RTOS threads
  - use full-range PWM for heater
  - enabled PID control for PWM (not optimized yet)
  - revised temperture probes scheduling
  - exclude useless tight loops
  - add tunable debugging messages
  - removed ALL blocking code, wiped arduino's `loop()` hooks, now all code is asynchronous
