/**
 *
 * ResistorDivider is a class with methods that can be used without initializing.
 *
 * It provides the various methods for determining one of the four variables for each calculation.
 *
 * @example
 *
 * cont { outputVoltage } = ResistorDivider.calcOutputVoltage(10, 1000, 1000);
 * cont { resistor1 } = ResistorDivider.calcResistor1(10, 5, 1000);
 * cont { resistor2 } = ResistorDivider.calcResistor2(10, 5, 1000);
 * cont { inputVoltage } = ResistorDivider.calcInputVoltage(5, 1000, 1000);
