Added MergeSort as new benchmark

[DkWeb]

I've added an implementation of MergeSort to the suite (dart-implementation, the derived dart.js-file and finally a javascript implementation). Surprisingly the javascript implementation seems to be twice as fast the dart counterpart.

Is spacing and indent messed up here? Can't tell if it's a code review UI thing.

Sorry for the inconvenience due the missing license and the wrong intent. This should be fixed now.

Have you signed the Google CLA? https://cla.developers.google.com/about/google-individual

[DkWeb]

Thanks for your fast response Seth. Actually I haven't signed the CLA up to now. I'll have a look at it tomorrow. At first sight google asks for a lot of personal information like the phone number and full address so I'll first have to check what they are allowed to do with this information ;-).

@sethladd Is it possible for me to use my CLA to help him get his code in?

@DkWeb If it's allowed, I could use my CLA so that your code is able to be merged.

[DkWeb]

@kaendfinger thanks for the offer. That would be great, because I really don't want to give Google all my personal information just to commit this simple benchmark.

@DkWeb No guarantees, but if they can do it I would be glad to help :)
