suggestion: link to sample project

[ZvikaZ]

Hi.

I'm using ECJ for some time now, and it's really great tool. However, it was quite difficult to start going, having initial simple project compiling and running, etc. Therefore, I've created a sample project, that can be cloned, and used as quick starting point.
