Extend README with examples of usage

[tomVeloso]

The project seam very interesting, would be nice to help people to more easly try it to add some lines on the readme with some simple examples of usage that underline the main features of the package.

Thanks for your interest! Yes, the README should be better. I'm quite busy these days so it will likely take me a while to get to this one, but I did want to acknowledge it.

Great! ... In the meanwhile, do you have any simple command line example to share with me? I'd love to start to try it ..
