Add "Getting Started" chapter about phpunit-documentation

[WynnChen]

This is absolutely necessary.

when I was a newbie to test, I had read a book about TDD,and had read PHPUnit's manual, so I had got a basic idea of TDD and I knew PHPUnit's features A,B,C,D... but when I tried to start test my project, sadly, I found that I did not know where to start. "How to get PHPUnit work together with my project? How to organize tests? How to write tests? How to run tests? ..." there was so many HOW TO. I spent a lot of time on try-and-error to get answers.

A walk through guide on a simple small project which have about 2 or 3 files will be very helpful. From such a example, we can learned how to write and organize tests for a project(instead of for a simple piece of code),and how to run tests,how to read result and get feedback.

+1. Current doc is detailed but a bit daunting by now.
Especially the info on 'where to put tests and then run them' is dispersed in many chapters (imho)
