 *  Converts from single or compound unit to single, compound or mixed units.

 *
 *  DESIGN:
 *    This class uses `UnitsConverter` in order to perform the single converter (i.e. converters from a
 *    single unit to another single unit). Therefore, `ComplexUnitsConverter` class contains multiple
 *    instances of the `UnitsConverter` to perform the conversion.
