@FunctionalInterface public interface Convertlet<F,T>
A Convertlet provides a single conversion from an object of a certain type to an object of a different type.

Convertlets are provided by ConversionProvider in an ArooaDescriptor.

Convertlets are used in sequences. A conversion from Float to Integer uses to Convertlets. Float to Number and Number to Integer. If a convertlet isn't to be used as part of a sequence it should be declared as a FinalConvertlet.

A Convertlet can always assume that they will not be used for an inappropriate conversion and so do not have to do any type checking.
