abstract interface
private pure function nearest_func(this, item, subtraction)

Type	Intent		Name
class(data_set),	intent(in)	::	this
class(*),	intent(in)	::	item	The value which those in the set are being compared to
procedure(subtraction_func)		::	subtraction	A function determining the magnitude of the difference between two items

The value from the set which, when passed to subtraction with item as the other argument, returns the smallest value
