/**
* A {@link Comparator} that is also {@link Serializable}.
*
* You can create a serializable comparator from a regular comparator through a
* method reference by appending ::compare. For example
* SerializableComparator<Employee>
* comparator = Comparator.comparing(Employee::getFirstName)::compare.
* The resulting comparator will in most cases cause exceptions if it is
* actually being serialized, but this construct will enable using the
* shorthands in {@link Comparator} in applications where session will not be
* serialized.
