> The indexOf methods search for a single entry in an array.
> This works fine when only the first matching entry is needed, however it is not so efficient
when all matches are needed (because of the setup/teardown overheads).
> It might be useful to introduce an indexesOf method that returns a BitSet containing
all the matches.
> This can then be used in the removeAllOccurrences methods.
