Comparing(IFunction)
Accepts a function that extracts a java.lang.Comparable
Comparable sort key from a type T, and returns a Comparator<T> that compares by that sort key.

the function used to extract the Comparable sort key
Returns
a comparator that compares by an extracted key

Remarks
Accepts a function that extracts a java.lang.Comparable Comparable sort key from a type T, and returns a Comparator<T> that compares by that sort key.
The returned comparator is serializable if the specified function is also serializable.
