Add a QUICKSTART.md

[lolocohen]

What do you propose?

The idea is to create a quick start document at the root of the repo, to illustrate how to quickly get started with JPPF, like an end-to-end HelloWorld. This would include how to setup and start a grid, full code example and expected output.

We shouldalso add a link to it in the main readme.md

What are the expected benefits and drawbacks?

The expectation is to provide an easy starting point without having to read tons of documentation.
