/** Test accessor that multiplies its input by a scale factor.
* This is a modified copy of TestGain.js
*
* First, the parameter is initialized to a different value.
*
* Second, there is an additional output, that sends the opposite of the
* obtained value. This second output is echoed using console.log.
*
* Third, there are 2 realized features, witch are 'gain' and 'opposite'.
*
* @accessor mutable/TestGain2
* @param gain The gain, a number with default 4.
* @param input The input, a number with default 0.
* @param scaled The output, the result of input * gain.
