Scaler
This function block performs the calculation y:= mx + b.
m is determined by the slope of a line specified by Cal_X1, Cal_Y1, Cal_X2, Cal_Y2.
x is the 'Input'
b is determined by calculating the Y intercept of the line.
This function can be used with temperature sensors or any analog value that must be adjusted before further
processing takes place.
