Source code to reproduce miniboxed stream numbers

[VladUreche]

The only significant change is the addition of the Numeric trait
that is required for obtaining the best performance (it cuts down
the benchmark time by 50-100%). The rest is just the same source
code, modulo some whitespace my editor f'd up.

The Numeric issue is tracked here:
miniboxing/miniboxing-plugin#154

And the numbers I got were:

Review by @biboudis, hope you like it :)

@biboudis, do you mind if we make scala-streams a case study on the miniboxing website?

[biboudis]

Not at all @VladUreche, feel free to add it on the miniboxing website. You have my full support.

[biboudis]

Before merging it @VladUreche a naive question: don't you mind that I have annotated with specialized and not with miniboxed? Shouldn't we use @miniboxed?

[VladUreche]

@biboudis: No, no problem at all. -P:minibox:mark-all will wipe @specialized and make it @miniboxed anyway :D

Well, we'll need to write this together. But not now, there are more important matters.

[VladUreche]

👍

[biboudis]

Although I like the annotation to be specified explicitly so I will update
it. ;-)

Knock yourself out :)
