public interface Function<F,T>
StringToIntegerFunction may implement
 Function<String,Integer> and transform integers in String
 format to Integer format.
 The transformation on the source object does not necessarily result in
 an object of a different type.  For example, a
 FarenheitToCelciusFunction may implement
 Function<Float,Float>.
 
Implementors of Function which may cause side effects upon evaluation are strongly encouraged to state this fact clearly in their API documentation.
