mapping
Defines a mapping for values within the given input range. This method call should be immediately followed by .toOutputRange, eg mappingInputRange(1,
2).toOutputRange(3, 4), which will return the unit builder for continued chaining.
Return
a builder object used to define the output range
Parameters
min
the minimum input value (does not have to be absolute)
max
the maximum output value (does not have to be absolute)
