SequencableCollection>>p3PrintUsing: delegate on: stream

[arnsholt]

In a project I'm working on, I've added the following extension method, which seems like a good candidate to add to this library instead:

SequencableCollection>>p3PrintUsing: delegate on: aStream

	delegate printValuesArray: self on: aStream

Hi Arne,

Thanks for the feedback and the suggestion.

There was a reason why I created P3ValuesArray and why I did not implement the method on SequenceableCollection, but I can't remember.

Furthermore, I tried your suggestion and replaced all usages of P3ValuesArray and everything kept on working fine, at least all tests were green.

So I am going to commit a change and we'll see how it goes.
