/*
The following methods perform conversions to and from the base unit of a unit class's dimension. Each unit is defined against the base unit for the dimension to which the unit belongs.
These methods are implemented differently depending on the type of conversion. The default implementation in NSUnitConverter simply returns the value.
These methods exist for the sole purpose of creating custom conversions for units in order to support converting a value from one kind of unit to another in the same dimension. NSUnitConverter is an abstract class that is meant to be subclassed. There is no need to call these methods directly to do a conversion -- the correct way to convert a measurement is to use [NSMeasurement measurementByConvertingToUnit:]. measurementByConvertingToUnit: uses the following 2 methods internally to perform the conversion.
When creating a custom unit converter, you must override these two methods to implement the conversion to and from a value in terms of a unit and the corresponding value in terms of the base unit of that unit's dimension in order for conversion to work correctly.
