/**
MapSensor - class-wrapper allows to map
a signal value of origin Sensor instance.
Re-maps the signal from one range to another.
That is, a signal of fromLow would get mapped to toLow,
a signal of fromHigh to toHigh, signals in-between to signals in-between, etc.
Instantiation:
Sensor* mapSensor = new MapSensor(
SENSOR,
FROM_LOW, FROM_HIGH,
TO_LOW, TO_HIGH,
);
Where,
SENSOR - origin Sensor instance.
FROM_LOW - the lower bound of the value’s CURRENT range
FROM_HIGH - the upper bound of the value’s CURRENT range
TO_LOW - the lower bound of the value’s TARGET range
TO_HIGH - the upper bound of the value’s TARGET range
Read signal:
int value = mapSensor->read();
v.1.3.3
- optimized read(*) method;
- updated documentation.

Created by Yurii Salimov, May, 2018.
Released into the public domain.
