> public method clone is implemented by creating a new instance through one of 
> the class Constructors, and then assigning values as required through the 
> setter methods.
> This means that any subclasses of the Option class will not return a true 
> clone, but a new Option instance instead.
> A proper implementation of clone should use super.clone() to create a new 
> instance, rather than calling the class constructor.  This allows shallows 
> clones to propogate correctly down to subclasses.
