Yes, I would like to encourage people to not use the KeySelectors. The
implementation is cumbersome and expressions already provide good performance
and should only get better once we have generated code for expression
comparators.
> Add Java example program with KeySelectors

> Fix For: pre-apache
>
>
> We need a Java example program that shows the use of `KeySelector` functions.
> Alternatively we could modify an existing program to do this.
> The new example program should follow the general layout of the other example
> programs, i.e., run without parameters on default data, have the same code
> structure, etc.
