#158 Use all processors

[David Pérez]

I have an eight core CPU, and when running ProGuard, I see that 1 core uses 100% and the other ones are idle.

I'm learning with the Scala language to allow parallel processing by using Reactive programming techniques.

Thanks for your suggestion. Although ProGuard's code is quite nice, parallellizing its many operations is definitely non-trivial.

When optimizing, the best place to start is the slowest operation. Please look into parallelizing the following operation. This is the slowest operation of all the operations that Proguard does.
