Temperature class

Represents a "thermometer" temperature.

This is distinguished from a change in temperature because of the fact that temperature scales are not zero-based. To represent a change in temperature instead, and for an in-depth explanation of this requirement, see the TemperatureChange class documentation.

Several operations on the Temperature class work with TemperatureChange instances instead of Temperature instances. This is because the natural way to think about those operations is in terms of temperature changes. For example, the + operator applies a change in temperature rather than a "thermometer" temperature. While physicists may intend to actually add two "thermometer" temperatures together in some cases, this is not the common meaning of "adding temperature," so the more esoteric uses are supported with special methods rather than the built-in operators. Pay special attention to the operations in this class to ensure proper use of the library. The type system should catch most errors, e.g. adding together two "thermometer" temperatures with the + operator.
