 *  This (temp.[ch]) code links an analog input channel and a conversion function to a temperature sensor.
 *  At least, a sensor for the extruder needs to be defined. A sensor for a heated bed is optional.
 *  The sensors will be used by the heater code and might be used by other temperature sensing/logging code.
