NumExtender class

Wrapper class for extensions on num types.

The main purpose is to limit the legal syntax to things that make sense, in particular for extensions that make use of an SI prefix. For example, if we were to have the prefixes return another num instead, the following would be possible, but not necessarily desirable:

a = 3.kilo.meters;       // Sensible.
b = 3.kilo.kilo.meters;  // Confusing! Prefixes should not be chained.
c = 3.kilo.floor();      // Confusing! Other methods on num should not be used.
d = 3.kilo;              // Confusing! Can be used anywhere a num is required.

Having the prefix extensions return instances of this class instead of num prevents all but the first usage demonstrated above.
