Common test suite

[szlend]

It would make sense to run a common test suite against all the solutions through stdin or something like that. Either that or make the solutions also test the empty case (compress("") == ""). I've ran into solutions where the empty case resulted in compress("") == "0" while prototyping, and I wouldn't be surprised if some existing or future submissions had the same issue.

It is a good point and a valid concern. To be honest; it was not needed before as there weren't so many languages or solutions, so perhaps the time has arrived. What do you think about @turboMaCk 's way of doing this via stding / args?
